There was a post yesterday explaining this. As I remember it is creo (creationist) vs. evo (evolutionist). These threads are referred to as crevo (combination of creo and evo). I hope I have that correct.
I rarely read these threads, and only tried to post a point of view that is a bit different from most (since I have a little experience in the area). I don't know why you refer to me as a creo. I'm not. Of course, you started right out making assumptions about me, which were not correct. I thought you were a rational person.
