I'm fairly certain that the field of gynecology contributes nothing to the evolution vs. creation debate, and if being skeptical of evolution defies common sense, then I suspect you haven't really studied the theory much. It isn't hard to poke holes in any of these theories (creation or evolution), and you don't need to visition the Sagan Institute or the ICR to do so. Every biological science is so intertwined with evolution at this point that you can't really separate the "theory" without all of biology falling to pieces. And yeah, I've studied evolution a bit. I've taken anthropology courses and do a fair amount of reading on the subject to keep somewhat current. And you should stop referring to it as a theory, particularly in the same sentence where you call creationism a "theory". One is a hypothesis (and a bad one at that) while the other is a fully-formed scientific theory. And yeah, evolution is pretty much common sense at this point. The mountains of evidence that supports it and the amount of science based on it is undeniable. It exists. It's real.
