How powerful is god?

So the virgin birth is pretty much out of the window.

No, no, no.
Virgin birth isn't even hard:
Virgin female defined as one who has not had sex with a male.

Virgin birth howto:
1) Collect ova from female (doesn't even have to be the same one)
2) Collect semen from male.
3) Mix
4) Wait a little while for embryos to show viability
5) Transfer embryo to VIRGIN uterus
6) Wait longer
7) C-section or vaginal delivery your choice.

Virgin birth: not a miracle....ever.
