Hey, you can look up the FACTS and determine that evolution happened too, but that doesn't stop creationists from squirming & denying everything at every turn.
Seriously, 20 years from now, after every participant in the Holocaust is gone, all that'll be left will be fossil evidence: Words on paper that some people claim were written in Germany in the 1940s by members of the government, and maybe films that some people claim show something significant about the fate of somebody or other. Who's to say that that stuff is really evidence? Unless you can reproduce it in a lab, it didn't happen. Right? :-)
What FACTS! All there is are theories, and many of them are under serious challenge by discoveries made in the various fields of SCIENCE. There is no EVIDENCE which proves evolution.
There is no fossil evidence to prove evolution.
