Whether or not I have a loss of critical thinking, there is no thinking required in the truth that no woman Xx can produce a man Xy by procreation unless a man, Xy, can contribute the y chromosome to the mix at conception, and even a human woman Xx, whom I credit as the ultimate creation [she arrives only late in the sixth day of the creative process [organizing], more to the point, because ex nihilo is a myth] activity occupying the previous counted days, well after the morning of man's creation on that sixth day, of however many hours those counted creation days were, because the Hebrew י֔וֹם [yo-wm] can be interpretted as a period of several different durations depending on context. And procreation in humans does not occur but by procreation, whether gametes are joined by coitus or by artificial insemination, and the result cannot be accomplished by parthenogenesis, because mammals cannot reproduce by that means whereas a few other species can, but parthenogenesis only produces females Xx, and once a human is conceived as either Xx or Xy, it cannot change its gender by any means, including hormone treatment, by surgery, or by thinking it is so, day-to-day.
As for the big wow!, that may be myth, as well, since that wish balloon can be ruptured by merely a small needle and you really do have a big, destructive, bang. Saying the universe is eternal goes backward in regression of time infinitely, just as progressively forward, infinitely. That's what eternity is; mathematically; a line, not a ray.
