The young Earth creationists usually claim that the Earth, and humanity, are about 6,000 years old, not 2,000 years old.

Friend's sister went this route.  I had a really hard time wrapping my head around this belief after all of the advances in paleontology we've seen in our lifetimes.  But I guess this is just explained away as false information planted by whatever.  Guess some people just don't want to believe in the true scale of our existence, as we understand it anyways.

This is why one of the parodies of this sort of thing among Pastafarians is to insist that the world was created last Tuesday, and everything before that is just fabrication.
