If God did indeed create us, why are we so similar to other primates?

I'm talking fingers, opposable thumbs, hair in similar areas, instincts, DNA, tool using ability, and the whole thing.

What makes you say that this isn't evolution and God just wasn't simply creative enough for his/her "prized possession" as some religions like to dictate us as?

I don't know, I just want to know someone's reasoning for ingoring all the similarities between humans and primates and saying it's God's work.
