I have always liked Occam's Razor as the deliberative choice in determining whether a philosophical point makes any sense. I think it should be applied to religions, specifically, in this instance, Christianity.
I find it hard to believe, particularly in the absence of proof, that Christianity is nothing more than a cult. Can you imagine the absurdity of a god impregnating a human woman. Impregnation is an event normally restricted to humans or lower forms of animal life. Why would a god engage in such behavior? First, consider it from a scientific viewpoint when we know how DNA is passed. Jesus would have had a god's XX or XY chromosome, whether a woman or man, respectively, and he would have had Mary's, his supposed Earthly mother's chromosome which, we know would have been XX. The conclusion we reach is that Jesus would have to be the product of an XY and XX chromosome, the XY deriving from god and the XX from Mary.
But why would god have to be male. I think it is unlikely that if there were a god, he would have to be male and have the XY chromosome which, if Jesus actually existed, would have to have been passed on to Jesus by his father. We have just anthropomorphized god, and in doing so, we have subjected him to all the frailties, vicissitudes and vagaries which mankind suffers.
Why would a god have to use such a pedestrian and predictable method of "recreating" his son on Earth. It is patently absurd.
