Two scenarios that may/may not happen.

[LuisDantas]

The first, being the guy of "hypothetical situations" which I'm known to family and friends, I wonder if the theory of Evolution was ever "proven" wrong, even though so far barely any of that happened, but considering that science demands that any hypothesis be falsifiable, there is a small chance that the theory of Evolution may be turned upside down, but as I said, this is just a hypothetical situation.

Frankly, that is not really possible. Among other reasons, because the theory has been falsified and corrected rather often, as one would expect.

At this point it would take an actual supernatural event - a major one - to put the ToE into any significant doubt.

So, based on that, does it follow that the creation story in the Abrahamic religions (Judaism, Christianity, and Islam) is true?

Can't think of any reason why it would.

Or rather, to the extent that it can conceivably ever be true, it is not really hindered by the ToE. Its chances of "being true" are as high as they are ever likely to.

Would your atheism be "shaken" if such far stretching hypothetical situation ever became a reality? And why?

No, of course not. Unless you are asking whether I would no longer be an atheist if God materialized in front of me or something? Then, no idea.

The second issue regarding Christ's existence.  I'm less enthusiastic to accept the claim that Jesus never existed. A good number of historians agree that he lived, also considering what I learned so far about history at university, we can't be 100% sure, after all, history is subjective. History is based on records from people who have their own agendas and biases, and it is a fact that they chose what or include and not include in their writings, it doesn't follow that something didn't happen or a person didn't exist just because some writings don't include such event or person. Also, there are chances that in the future we may find a good and reliable evidence for people that believed never to have existed. Therefore, it is safe not to be so "sure." What do you think of such argument?

I don't think there is a good case for the literal existence of the Jesus of the Bible. Far too much about him seems to be either tentative or all-out fable-like.
