im not sure that they are. im also pretty sure ive never seen proof of evolution. ive seen evidence that support those claims but ive seen evidence to support other theories that never panned out. remeber the people who claim this also can prove that the dinosaurs were killed by an asteroid. oh and then there are the ones who prove they were killed by a shift in the earths rotation. then there are the ones who prove that they were killed by a mega volcano. i hope you can follow the thinking there....
