A miracle is enough - Jesus in adult life used power from the Father to do so many miracles that one New Testament writer speculated that if all of them were written down the whole world might not suffice to hold all the books - that is far fetched but expresses the mega-plurality of Jesus during His ministry on earth.
Here is an approach from the other end - astoundingly unlikely but absolutely feasible in regular terms.
(a) Look up meiosis - it can make huge mistakes, and they tend to be fatal.
(b) BUT one possibility is that Mary was an XY female - this is known to happen, or XXY due to an extra sex chromosome winding up in the egg that became Mary.
(c) Now turn up the dial of meiosis playing oopsies with chromosomes - 47 chromosome Mary produces and egg cell with 46 chromosomes instead of 23 or 24, and the sex pair comes out XY - the “missing” 47th chromosome was one of the two X’s.
(d) The egg, fully populated with diploid 46 chromosomes, implants and becomes the Christ.
Long story short, if you look hard enough you can find clever side effects GOD enabled via evolution - and the meiosis kind of chromosome oopsy is in fact enough of an evolutionary advantage that it was there ahead of time, needing only a pair of tiny fiddles to achieve what God planned.
