Of course the night, the day, the ships, the rain, the cows, the beans, the dates, are proofs of God because everything has been created by God.
But in our 21st century the proofs of God are much more than what meets the eye. They are in astronomy, in physics, in genetics, in evolution. And all that is only at its beginning.
So...would you have liked the Quran to contain all of the 20th century knowledge as proof? The Quran is guidance for all of mankind, through all the ages. What good is genetics to a man living 1000 years ago?
Rather, the Quran guides us in what we need to know, how we need to act, and at the same time, guides us to the proof he exists.
You mentioned astromony and physics, I suppose you mean the complexities of creation of the universe, the balance and sheer design of everything from the smallest quarks to the biggest galaxies. Do you think, if this information was revealed 1400 years ago, anyone could understand them, let alone be convinced of a God through it?
Instead Allah, in his wisdom, reveals to us facts relating to creation, some of which I have posted. These facts are in perfect corrallation with science and modern knowledge, and some, you even admit you even admit you can't explain (smoke) and the others you attribute to similarities in knowledge with other eras. Yet, mathamatically, what is the probablities the Quran contains so many of these facts? So low to 0 it's not even worth mentioning.
That is what I compared, between the simplistic proofs from nature given by the Quran, and the incredible discoveries from nature that we are only beginning to read in its open book.
You consider them simplistic because you take them at face value. Yet the knowledge the Quran guides you too is much greater, and much deeper.
Since your currently reading the Quran, I simply pray you will have the truth shown to you (whatever it may be).
Although, I sincerely ask you to read the Quran under the pretence it's from God, even if you don't believe it is. If you read the Quran with a notebook looking for something you can bring up in a debate - what good will it do?
If you have another topic to debate with me Mansio, feel free to bring it up. However I suggest in a new thread, 10 pages on we haven't really achieved much.
Peace.
