Relativity talks of the warping of spacetime. say what would happen on a busy street if an individual pulled a spacetime warp? would he be invisible to others? would he be able to dissappear off the street at 9am and re appear at the same point on the street at 4pm (all in a flash)?

I don't really believe in evolution, at least human evolution, I know other animals evolve, it's a proven fact, but I'm still all for God created humans. But anyway my question is, if evolution really did happen, and chimps evolved into humans, then in a few million years, what are humans going to be? You know if we don't kill each other off before then.
