Just think back on when Columbus discovered the new world. Savages! Things that look like humans yet live like animals! With no clothes, no God, no sense of church or salvation. You can't even say that somehow Christianity arrived in the New World and then was lost -- it was just too isolated. (At least until the Mormons came along and solved that problem, but that's another story). As far as anybody was concerned, these were creatures that lived in an entirely alien way. Barely human, if that.<p>Lots more examples where that came from. Christianity adapted just fine. In fact, one of the major changes Christianity brought to the ancient world was the understanding that all bipedal hominids were equally deserving humans -- that was an unheard of concept before about 100AD. If history is a guide, there'll be a little backlash for a decade or two due to the strangeness and then somebody will be telling us how Jesus actually came to the Martians first back in 1 Billion B.C.<p>To say that religion will not survive wildly changing pictures of reality is to fail to understand religion's key concept: the creative group explanation for things that cannot be proven one way or another. Heck, religion is <i>custom-designed</i> by evolution especially for situations like dealing with E.T.
