I have never experienced anything like walking out onto the stage of an oversold venue and, before the first note is struck, realizing that there is not going to be enough oxygen for all of us.
If all the animals and man had been evolved in this ascendant manner, then there had been no first parents, no Eden, and no Fall. And if there had been no fall, then the entire historical fabric of Christianity, the story of the first sin and the reason for an atonement. . . collapsed like a house of cards.
