There is no proof of that. hoax or not, it's not important.
I agree with you friend. It does not matter from what we descended. We are what we are, and that is only what is important. Future is what we need to be concerned about, and this moment even more than future. I do not know why, but to some people it is really important to know how we came to this world, maybe it is too me a bit too. But i am ok with not knowing too.
Problem is that those evolutionists believe we will evolve in the future and create all kinds of harmful ideologies based on that false accusation. For example, Hitler.
