You apparently missed my point. I didn't mention creationism. I meant keep an open mind about the theory of evolution (which of course is actually many theories covering many topics).
I keep an open mind about evolution too. Indeed, if something comes along that explains the evidence and observations of all those diverse scientific disciplines far better than evolution, and has evidence and observation to support it that does not also support evolution, I'll ditch ol' Darwin in a New York minute. However, I have yet to see any such coming out of those who sit on the sidelines and carp.
