I don't recall where, but I remember reading about how geographic location affected the way UFOs and aliens were described by those who claimed to see or encounter them. As if to say that such things as UFOs and aliens are, in essence, a cultural phenomenon. Aliens "seen" in the USA were generally short, with grey skin and proportionally large heads and eyes, whereas those seen in... Norway (I think) were taller, had lighter skin and smaller heads. It was an interesting article.
"Well, evolution is a theory. It is also a fact. And facts and theories are different things, not rungs in a hierarchy of increasing certainty. Facts are the world's data. Theories are structures of ideas that explain and interpret facts. Facts don't go away when scientists debate rival theories to explain them. Einstein's theory of gravitation replaced Newton's in this century, but apples didn't suspend themselves in midair, pending the outcome. And humans evolved from ape- like ancestors whether they did so by Darwin's proposed mechanism or by some other yet to be discovered."
