Does God exist? Yes, there is a God, but of course simply saying that God exists does not mean there is one. The existence of God has been debated for centuries. Atheists deny him, or say they “lack belief in God.” For believers “believe in God” is part of their faith and faith is to believe in unseen. Does this prove the existence of God? Not really.

How do you “prove” there is a Great Being outside of our universe? Do we look for footprints in a riverbed? Do we examine evidence under a microscope and say, "A ha! There's God!"? That would be the wrong approach. If God exists, he would be beyond our universe, non-material, and transcendent. So, we would have to look for evidence that is consistent with a non-material and transcendent being. Several arguments can be used to logically prove the existence of God. Whatever argument you might accept or deny, it seems that your presuppositions are what determine if you believe in God or not. Atheists, of course, presuppose that God does not exist, that’s their faith. They can't "know" He doesn't exist, nor can they prove that in all the universe (or outside of it) there is no God. But, their atheism means they will deny any evidence or explanations used to affirm the existence of God. On the other hand, believers rely on the revelation of Scripture to tell them who God is. The reader should be an open minded person and should analyze the arguments presents later without any presuppositions.

We all knows the science has proven certain facts such as gravity, electromagnetic forces, composition of atoms, radio waves, speed of light, air or oxygen etc., which we can’t see for ourselves but we still believe in them. People used to believe that Sun is stationary but now we know that Sun revolves in its own orbit. How do we know all these facts and what these has to do with existence of God? One common misconception is that the religion is always at odds with science. This reminds me of two famous quotes about theists and atheists:

“A little knowledge of science makes man an atheist, but an in-depth study of science makes him a believer in God." - Francis Bacon.
"I can conceive how it might be possible for a man to look down upon the earth and be an atheist, but I cannot conceive how he could look up into the heavens and say there is no God." -- Abraham Lincoln
It is these established scientific facts and scientific methodology which makes us more believer in God than ever before. People few centuries ago may have relied heavily on philosophical arguments to prove the existence of God but today we can make use of both scientific and philosophical arguments to prove the existence of God.
Many of us know how the scientific methodology works. We make certain observations, and come up with a certain hypothesis which is tests based on different facts and thus come up with scientific laws or theories. I will use the same concept to build my argument and prove how existence of God is the best explanation that can be offered for some of facts we try to make sense of. Some of the arguments we can discuss are:

WHY DOES THE UNIVERSE OPERATE BY UNIFORM LAWS OF NATURE?
Much of life may seem uncertain, but look at what we can count on day after day: gravity remains consistent, a hot cup of coffee left on a counter will get cold, the earth rotates in the same 24 hours, and the speed of light doesn't change -- on earth or in galaxies far from us. How is it that we can identify laws of nature that never change? Why is the universe so orderly, so reliable?
Even the greatest scientists have been struck by how strange this is. There is no logical necessity for a universe that obeys rules, let alone one that abides by the rules of mathematics. This astonishment springs from the recognition that the universe doesn't have to behave this way. It is easy to imagine a universe in which conditions change unpredictably from instant to instant, or even a universe in which things pop in and out of existence.
Richard Feynman, a Nobel Prize winner for quantum electrodynamics, said, "Why nature is mathematical is a mystery...The fact that there are rules at all is a kind of miracle.”

THE DNA CODE INFORMS, PROGRAMS A CELL'S BEHAVIOR:
All instruction, all teaching, all training comes with intent. Someone who writes an instruction manual does so with purpose. Did you know that in every cell of our bodies there exists a very detailed instruction code, much like a miniature computer program? As you may know, a computer program is made up of ones and zeros, like this: 110010101011000. The way they are arranged tell the computer program what to do. The DNA code in each of our cells is very similar. It's made up of four chemicals that scientists abbreviate as A, T, G, and C. These are arranged in the human cell like this: CGTGTGACTCGCTCCTGAT and so on. There are three billion of these letters in every human cell!!
Well, just like you can program your phone to beep for specific reasons, DNA instructs the cell. DNA is a three-billion-lettered program telling the cell to act in a certain way. It is a full instruction manual.

Why is this so amazing? One has to ask....how did this information program wind up in each human cell? These are not just chemicals. These are chemicals that instruct, that code in a very detailed way exactly how the person's body should develop.
Natural, biological causes are completely lacking as an explanation when programmed information is involved. You cannot find instruction, precise information like this, without someone intentionally constructing it.

THE COMPLEXITY OF OUR PLANET POINTS TO A DELIBERATE DESIGNER WHO NOT ONLY CREATED OUR UNIVERSE, BUT SUSTAINS IT TODAY.
Many examples showing God's design could be given, possibly with no end. But here are a few:
The Earth...its size is perfect. The Earth's size and corresponding gravity holds a thin layer of mostly nitrogen and oxygen gases, only extending about 50 miles above the Earth's surface. If Earth were smaller, an atmosphere would be impossible, like the planet Mercury. If Earth were larger, its atmosphere would contain free hydrogen, like Jupiter. Earth is the only known planet equipped with an atmosphere of the right mixture of gases to sustain plant, animal and human life.
The Earth is located the right distance from the sun. Consider the temperature swings we encounter, roughly -30 degrees to +120 degrees. If the Earth were any further away from the sun, we would all freeze. Any closer and we would burn up. Even a fractional variance in the Earth's position to the sun would make life on Earth impossible. The Earth remains this perfect distance from the sun while it rotates around the sun at a speed of nearly 67,000 mph. It is also rotating on its axis, allowing the entire surface of the Earth to be properly warmed and cooled every day.
And our moon is the perfect size and distance from the Earth for its gravitational pull. The moon creates important ocean tides and movement so ocean waters do not stagnate, and yet our massive oceans are restrained from spilling over across the continents.
Water...colorless, odorless and without taste, and yet no living thing can survive without it. Plants, animals and human beings consist mostly of water (about two-thirds of the human body is water). You'll see why the characteristics of water are uniquely suited to life:
It has wide margin between its boiling point and freezing point. Water allows us to live in an environment of fluctuating temperature changes, while keeping our bodies a steady 98.6 degrees. Water is a universal solvent. This property of water means that various chemicals, minerals and nutrients can be carried throughout our bodies and into the smallest blood vessels.
Water is also chemically neutral. Without affecting the makeup of the substances it carries, water enables food, medicines and minerals to be absorbed and used by the body.
Water has a unique surface tension. Water in plants can therefore flow upward against gravity, bringing life-giving water and nutrients to the top of even the tallest trees.
Water freezes from the top down and floats, so fish can live in the winter.
Ninety-seven percent of the Earth's water is in the oceans. But on our Earth, there is a system designed which removes salt from the water and then distributes that water throughout the globe. Evaporation takes the ocean waters, leaving the salt, and forms clouds which are easily moved by the wind to disperse water over the land, for vegetation, animals and people. It is a system of purification and supply that sustains life on this planet, a system of recycled and reused water.
The human brain...simultaneously processes an amazing amount of information. Your brain takes in all the colors and objects you see, the temperature around you, the pressure of your feet against the floor, the sounds around you, the dryness of your mouth, even the texture of your keyboard. Your brain holds and processes all your emotions, thoughts and memories. At the same time your brain keeps track of the ongoing functions of your body like your breathing pattern, eyelid movement, hunger and movement of the muscles in your hands.
The human brain processes more than a million messages a second. Your brain weighs the importance of all this data, filtering out the relatively unimportant. This screening function is what allows you to focus and operate effectively in your world. The brain functions differently than other organs. There is an intelligence to it, the ability to reason, to produce feelings, to dream and plan, to take action, and relate to other people.
The eye...can distinguish among seven million colors. It has automatic focusing and handles an astounding 1.5 million messages -- simultaneously. Evolution focuses on mutations and changes from and within existing organisms. Yet evolution alone does not fully explain the initial source of the eye or the brain -- the start of living organisms from nonliving matter.

THE EXISTENCE OF OBJECTIVE MORAL OBLIGATIONS IS BETTER EXPLAINED BY THE EXISTENCE OF GOD.
People experience a sense of morality that leads them to hold strongly that certain things are right or wrong for all people in all cultures. For example, it is wrong to torture another person just for fun. It is wrong for me today. It is wrong for a citizen of the Philippines and it was wrong for someone living in 500 BC. If it is true that it is wrong to torture another person just for fun, then our moral sense picks up something real and objective about morality.
Some philosophers have argued that without God there can be no objective morality at all. In fact, I used to argue for this claim myself. I have changed my mind about this point. I think there can be objective moral goods without God. For example, Aristotle believed that there are objective facts concerning what helps human beings flourish. Human flourishing is clearly a moral good. Thus, there can be some objective moral goods without God. It is more difficult to find room for objective moral obligations without God.
What is the difference between a moral good and a moral obligation? A moral good is a state or situation that, morally, is better to have than not. We might think that it is a better situation, morally, if a person can fulfill some of her potential than if she cannot fulfill any of it. A moral obligation is a duty. If I have a moral obligation to do some action, then I have a duty to perform it. If I refrain from doing the action, I fail at one of my duties, and I am in that sense blameworthy.
What I will argue is that objective moral obligation is better explained by the existence of God than by atheist stories. I will not argue that objective moral obligations are impossible without God. I will argue they are more likely if God exists. If I am correct, objective moral obligations will be evidence for God’s existence.
Before I go any further, I must make it clear that I am not claiming that one must believe in God in order to be moral. I am not claiming that statistically those who believe in God are more moral than those who do not. I am also not claiming that our knowledge of morality depends upon God. This argument is to the effect that objective moral obligations themselves are surprising in a universe without God. They do not fit.
We have different kinds of obligations. Some are prudential, such as “you should prepare for the final exam.” Others have to do with playing a game such as “you cannot move your bishop along the horizontal.” Others are moral. One fact that separates moral obligations from other obligations is that non-moral obligations are actually conditionals. For example, you should prepare for the final exam if you want to do well in the class. You cannot more your bishop along the horizontal if you want to play chess according to the rules.
We can call this kind of obligations conditional obligations. There are two things to observe about conditional conditions. First, if the condition is not fulfilled, the obligation does not hold. Second, it is up to the person involved if she wants to fulfill the condition. So, it is up to you if you want to play chess according to the rules. If you do want to play according to the rules, then you have the obligation not to move the bishop across the horizontal. If you do not care about doing well in the class, you don’t have the obligation to prepare for the final exam. It is up to you if you care.
Moral obligations are not conditional in this way. Suppose you are in a situation in which it would be morally wrong to lie. Someone might want to say that your obligation is conditional. In other words, the moral claim is the following: “If you want to be moral, you must tell the truth in this particular situation.” This sentence is true. If you do not speak the truth, you are not acting morally in that situation. Notice that you are free to reject the condition. You can decide to act in a way that is not moral. If you decide to reject the condition, however, you are not released from the obligation. You may choose to act to fulfill your obligation or not to fulfill it. Either way, the obligation still holds. This observation about moral obligation is a feature of our widely shared concept of moral obligations. It is part of what it means to be under such an obligation.
Part of what makes moral obligations objective is this fact that whether they apply is not up to us. We are not free to refuse to “play the morality game” the way we can refuse to play chess and move the pieces however we want.
There is one more thing to notice about our different kinds of obligations. Conditional obligations are related to conditional purposes. If my purpose is to do well in a class, the obligation to study is binding on me. If my purpose is to play chess according to the rules, the obligation about how I may move my pieces holds. As I said, these conditions are in some sense up to us. Therefore, the purposes are up to us. We can opt in or opt out. Moral obligations seem to be related to purpose as well. If we want to act the way a human being ought to act, we should not lie in a specific situation. The purpose in an unconditional obligation is an unconditional purpose. It is not up to me but it holds.
Given these observations about the nature of obligations, and about moral obligations in particular, we can see that the existence of objective moral obligations makes sense if God is real. They might not be impossible without God, but it is surprising that the universe would develop objective, unconditional purposes for human beings simply by accident.
God, if he exists, is a powerful person who creates the universe (and human beings) for his own reasons. Some of these reasons constitute human purpose. Islam, for example, specifies that part of God’s purposes in creating us is that we would embody and practice various virtues that reflect his own goodness. In this view, it is no surprise that there are unconditional obligations.
If God does not exist, then, although there is a causal story about how human beings emerged, these causes do not provide reasons or purpose for our existence. Objective moral obligations are surprising on this view.

THE EXISTENCE OF THE UNIVERSE IS BETTER EXPLAINED BY THE EXISTENCE OF GOD.
I will begin by laying out the argument:
There are things which come into existence.
Everything which comes into existence is caused to exist by something else.
There cannot be an infinite series of past causes.
Therefore, there exists a first cause which did not come into existence. In other words, the first cause always existed.
Let us look at each of the steps in the argument:
Premise 1. “There are things which come into existence.”
Many things have come into existence. This post is coming into existence as I write it. You came into existence and so did I. This premise is not controversial.
Premise 2. “Everything which comes into existence is caused to exist by something else.”
It is obvious that nothing can cause itself to come into existence. Anything that causes itself to come into existence has to exist before it exists. This is impossible. Perhaps something can come into existence from nothing without any cause whatsoever. Can a thing just pop into existence with absolutely no cause? This also does not seem reasonable.
When my children were young, they would sometimes draw on the walls. If I walked into the dining room and saw a picture of Pinky and the Brain drawn on the wall in Permanent Magic Marker I would have asked “Where did this picture come from?” My son Belal might have said “It came from nothing, Dad. Nothing caused it. It just popped there. I think it is quite strange — don’t you?” Would I have accepted this? No! Things do not come into existence from nothing without cause. So, we have good reason to think that premise two is true. Everything which comes into existence is caused to exist by something else.
Premise 3. “There cannot be an infinite series of past causes.”
Is the series of past causes infinite? Can the universe have an infinite past? The answer is that it cannot. First, there are philosophical reasons to think the past cannot be infinite. Second, there are scientific reasons which support this view.
Philosophical Reasons:
Why can’t the past be infinite? The answer is that it is impossible to complete an infinite series by addition. The series of past events is complete. Think of this mathematical fact. Why is it impossible to count to infinity? It is impossible because, no matter how long you count, you will always be at a finite number. It is impossible to complete an actual infinite by successive addition.
The past is complete. This claim means that the entire series of past events ends now. It ends today. Tomorrow is not part of the series of past events. The series of past events does not extend into the future. It is complete at the present. If it is impossible to complete an infinite series by successive addition (as it is impossible to count to infinity) the past cannot be infinite. If the past is finite, that is, if it had a beginning, then the universe had a beginning. We have strong philosophical reason to reject the claim that the universe has always existed.
Scientific Reasons:
I will not develop these. Rather, I will simply point them out.
Big Bang theory does not prove that the universe had a beginning, but it supports this claim.
The second law of thermodynamics does not prove that the universe had a beginning but it also supports this claim.
We can see that we have good philosophical and scientific reasons to reject the idea that the Universe has always existed.
About the Universe, there are only three alternatives:
1. The universe has always existed. It has an infinite past.
2. The universe was popped into existence from nothing with absolutely no cause.
3. The universe was caused to exist by something outside it.
We have strong reason to reject the first two alternatives.
Alternative Three is the most reasonable. There was a first cause. This cause existed eternally. It initiated the big bang and created the universe. Now what can we know about this cause? Why think the cause is God? I will briefly sketch a few implications.
First, the first cause is not a part of the space-time physical universe because it caused the space time universe to begin. Therefore, it is outside of space and time. It is not physical. Second, it has a great deal of power. Third, it is a personal agent. This means it is not an inert force but it must have aspects of person hood; namely, that it wills. How do we know this? This is because it is the best answer to the question of why the Big Bang happened when it did. Why not sooner? Why not later? All of the conditions for producing the Big Bang existed from eternity. The only kind of cause we know of that can initiate an effect when all of the conditions are already present is the will of a personal agent.
I have not argued that it is logically impossible that the universe popped into existence from nothing without cause. I have argued that it is more reasonable to hold that it has a cause and that this cause is a non-physical personal agent — God.
So, it seems that the first argument is fairly strong. The existence of the universe is better explained by the existence of God.
I have briefly presented several arguments for the existence of God. Of course, there are many other arguments to consider on both sides, and each could be developed in much more detail. I have presented enough, I think, to suggest that it is more reasonable to believe that God exists than that He does not exist. I have not claimed to prove with mathematical certainty that God exists. I have, however, provided good reasons to think that He does. If someone wishes to argue successfully that God does not exist, he must first, provide an answer for each of my arguments and second, he must offer arguments that God does not exist. Until He does this, we can conclude that we have good reason to claim that God does exist.
Remember this is the first step, once one is convinced that God does exist then we have our next battle to fight which is how many gods are there – one or many? The answer is very simple, God has to be ONE otherwise there will a chaos. Furthermore, this God should have given us some guidance to live our lives and should have defined the purpose of our lives on this planet. This will be start of a new journey for many who may have come to the conclusion that God does exist and has sent His Divine guidance for us to follow. You can look into all the religions in the world and come to your own conclusion but I will share what I believe to the true religion. My years of research shows that Islam is the only true religion.
