There is a 98% DNA match among humans and the great apes. That screams branch off.
We have vestigial tails during our early development that just screams that we had tails at one point in time that we used.
A virus building a 'coat' of food so that it will continue to survive without a host is an example of evolution(hence a virus becomes airborne). Evolution is basically adaptation techniques to keep your lineage going. Every species crawling on this planet has something like this going for their lineage or they wouldn't keep surviving. Your immune system is a testament to evolution.
How any thinking person can look at this and say, "It proves nothing." is beyond me. I would take critics of evolution seriously if they only had a clue. Instead they always seek out some video or reference some article. They can't discuss it one on one because they never actually take the time to study it themselves. Theory doesn't mean what you guys think it means in this case. But once again, no effort has been put into actually studying the subject at hand, only blind hatred and allegiance. Next you'll tell me the Earth's continents never move and that tectonic plates don't exist. Next you'll tell me the meteorite that killed the Dinosaurs doesn't exist even though we found the crater(by accident even) and visual fossilized proof to go along with the fact.
As far as the Big Bang, there is visual evidence that the Universe is expanding(redshifting and blueshifting). Hence it had to have been at a smaller state at some point. Now beyond what that smaller state was like, I'll give it to you guys that that's harder to call. But then how do you explain the Hubble Ultra Deep Field image? More theories I guess even though it's visual evidence.....
