Jeri, I don't think that "Lucy" was ever considered to be that missing link but I stand to be corrected on that.There was the famous missing link one which proved to be a hoax, using bones of both humans and apes. I think it was called the Piltdown Man.
Another problem that I have with religion is that there appear to be noticible peoriods of activity followed by inactivity - how's about the Star in Bethlehem was a space ship?
