Check out this video of a chimpanzee playing Pacman. OK he's not very good at it, but how many other animals would even understand they're moving something on the screen? Just look at his face at the end of the clip, so human.
What is the chance that we would have other animals that are just so human on the Earth? Evolution can explain it and predicts species would be very similar to other species.
Why would god create species so similar, with a few minor tweaks here and there that guy could be human and could play decent games like Civilization 4? Why would god be so cruel to limit these guys brains? What kind of god is that?
To me that speaks of evolution, of that we both share a common ancestor about 8 million years ago. Of course you could just argue god did it, but that attitude isn't going to cure diseases and result in a greater understanding of the cosmos.
