Martin, you're just being silly about the immaculate conception thing by insisting on interpreting it as a literal, physical concept.

There's a misunderstanding of a term here. "Immaculate conception" is not just another way of referring to a virgin birth, or the inception thereof.

"Immaculate conception" doesn't even refer to Jesus. It refers to Mary, who was, under the doctrine of immaculate conception, born without the taint of original sin.
