“Over and over again in astronomy, cosmic collisions are invoked as a sort of magic wand to rescue evolutionary theories from the facts. The planet Uranus is tilted over, but evolution says it can’t be—therefore, long ago something hit it and knocked it over. Venus’s rotation contradicts evolutionary predictions—therefore, long ago something hit it and spun it round the opposite way.
Mars’ atmosphere is too thin for evolutionist tastes—therefore, it used to be thicker, but long ago something hit Mars and stripped most of it away. Mercury is too dense for evolution—therefore, long ago something hit it and conveniently removed the lighter parts. Evolutionists wave their collision-wand at will, and yet mock as “unscientific” the Christian belief in a one-off catastrophic global Flood, despite the abundant physical and historical evidence for it.”
