Not too easy. Not too difficult.
The evolutionary history of human beings can indeed be controversial, here is a course to engage in that controversy. Where did we come from? Who came before us? Where is evolution going? Why do we look like the way that we do?
Seriously, there were so many primates that were so eerily similar to humans. Check out Homo ergaster for a good example. The looked like us, and possibly acted like us. For instance, it's possible that the Neanderthals buried their dead for spiritual purposes. If that's not "human" then I don't know what is.
