It's credible to me, because the story checks out. The facts are the evidence that support the story. There is Isaiah's testimony and that contained in the Gospels. I don't take what's said about the virgin birth based solely on what is written about it alone. Jesus claimed to be God. He's the only one in history that ever showed up in person and did so. It's His claim that I've looked at and evaluated for truth. With that, the rest fits in.
The miraculous birth doesn't fit in at all. There's no testimony of it written in scripture and it doesn't make sense to me. It would in fact say that God did not become man. There's no point to being carried and born of woman if God's just going to beam out anyway. It's illogical. Also, all I've seen that justifies the claim is that her hymen remained intact. That's also ridiculous to me. There's no point to it. I suppose the afterbirth beamed out too.
" If her pregnancy was without physical entry, why would a Birth lacking physical exit not be possible?"
The physical entry refers to intercourse only. In order for the birth to occur, something physical had to happen. What it was in particular, I don't know. Now a physical exit is not possible, because Jesus was a real physical baby subject to the laws of physics. As long as He became a man, he remained one in the same way as all other men. Of course the conception was also subject to the laws of physics, that does not mean I know the particulars.
" A 'viable diploid egg' is an oxymoron, spunkets. An egg is a haploid, by definition,"
Normally the diploid egg is called a fertilized egg. In this case, I just called it a viable diploid egg, because it wasn't fertilized in any humanly capable way. Those things split and become zygotes, and so on...
Just as when Jesus appeard through a closed door. God is not subject to laws of nature.
it wasn't fertilized in any humanly capable way
Where do you find in the Scriputre that her egg was "fertilized?" You are calling light-through-the-glass an invention and you are giving detailed bilogical "facts" about Incarnation.
Again, fertilized egg consists of DNA from both parents. Are you suggesting now also that in thi case the haploid was mysteriously made into a diploid (whose DNA?) or else Jesus would be a female, that is – if a halpoid could progress into a human being.
