Lets face it, Christianity is based on the beliefe that a god created a man and a woman. Now its said in the bible that this couple had two sons Cain and Able, (i do believe there was a third son whose name i have forgotten),  Well ( and i guess you know where this is heading), just exactlly can we now have a planets sized population of well over 6 Billion people from ONE MOTHER, ONE FATHER, and TWO/THREE SON's...............................please dont tell me they ...............no dont go there.
