Great question. It is not. Evolution is mostly wishful thinking disguised as science.
It absolutely isn´t and you should feel bad for even suggesting so.
It is true and happening as we speak, take some evolution classes to educate youself.
You won´t be able to ignore it´s existence (if you have a decently working brain and aren´t a brainwashed fanatic like ...someone else ) when you know the ins and outs of it.
We know far too much. Everything is based on logic and not based on "wishful thinking".
The wishful thinking is on the other side of the debate.
