The site states: That all life on earth evolved from a single common ancestor is a fact .
Why should all life on earth evolve from a single common ancestor? if something can evolve by itself, then it's very much possible that many things evolve and not just one. In that case, life on earth would not have a single common ancestor.
I agree. It may have had multiple. But if you trace the evidence you find that these multiple would have been very similar to each other, because all the evidence points to common ancestry, common dna, common structures, etc.
whether you can discard a theory or not doesn't make it right or wrong.
That is is falsifiable and we haven't been able to find any evidence to falsify it, despite repeated findings, is evidence that it is true.
And no, that we can discard and modify it doesn't make it right or wrong. But it does make it a theory worth having and revising. It is an honest and open approach to solving the puzzle. Declaring you have all the answers by fiat isn't.
some things are self-evident truths while others are not. Existence of God is a self-evident truth.
No it isn't. It is an assumption you make, for which you provide no evidence, and only faith. It may seem obvious to you, but does is not also seem obvious that the world is flat and that the sun goes around the earth? We have found evidence otherwise and we have abandoned these assumptions.
yes assumptions are made in the theory of evolution.
Assumptions are made, yes. And they should be tested where possible.
However, you claimed:
Scientists observe creation and assume that organisms came into being by themselves and then evolved.
This is not true.
take the statement from the site you gave:
Fossils provide a snapshot of what life on earth looked like at various stages in the past. These can be dated using methods such as Carbon-14 dating. What the fossil record shows is that, as you look deeper and deeper back in time, species become much less complex and fewer different types of species can be found. This suggests that life started off simple and then gradually evolved into the various different forms we see today.
Note the word "suggest."
That doesn't denote an assumption. That denotes inconclusive evidence.
Although animals are very different from one another, there are a lot of similarities as well. For example, all mammals have a similar bone structure in their limbs, even though the bones are different sizes. This indicates that there was once an original animal with that structure and that that structure eventually evolved into many different forms. Other similarities in anatomy structure can be seen in insects and plants.
it indicates but we don't know for sure that that was what happened because we didn't witness it. thus this is an assumption and not a proven fact.
No. that isn't an assumption either. That is a hypothesis backed up with some more inconclusive evidence (that animals have similar anatomical structures).
Species in the old world (Europe, Asia, and Africa) are often quite different than species in the new world (North & South America). Species in Australia and other remote islands (e.g. - kangaroos) are especially unique. This indicates that as animals spread out over the earth, they evolved differently in different locations.
Again why should animals with one common ancestor spread out to different parts of the world? why didn't they evolve from separate ancestors in each part of the world? If things could evolve by themselves without God causing it, then there would be many and not one common ancestor.
They did evolve separately. That is the point. The further apart they are the more different they are, but the further back you go in each area's fossil record, the more similarities you see between them. That fits with the theory of a common ancestor that migrated to both places and then evolved seperately in those places.
ERV's are a special type of virus that infects DNA. They continue to get copied from generation to generation even when they no longer cause damage and are thus a type of fossil in our DNA. When you compare the DNA of humans and chimpanzees, you will find the exact same ERV's in the exact same locations, something that simply could not have happened by chance. Again, this indicates that humans and chimpanzees share a common ancestor.
What about their position in other organism? Isn't it possible that they infect similar parts of DNA?
It isn't that they infected similar parts of DNA. It is that they are the exact same.
I don't believe any of these lines of evidence to be absolutely conclusive, but taken together they do make a pretty good case. And this definitely answers your question

Is there any more proof for evolution than there is for theism?
Yes. There certainly is. You've got all this for evolution. For theistic claims you've got nothing but "Its self evident!!"
