How did the moon form? Nobody quite knows with absolute certainty. The creationists think they know – Goddidit – and they think that any other attempt at the answer is baloney. Hence Moday’s article from Brian Thomas, Impact Theory of Moon’s Origin Fails, which opens:
Secular scientists used to regard the planetary collision theory as a triumph in explaining several of the moon’s specific arrangements. But newfound facts severely debilitate this lunar impact origins theory.
According to this new theory, an early Earth collided at a glancing angle with a planet that was one or two times the mass of Mars. Some of the debris launched into orbit around Earth and somehow collected to form the moon. This could explain the moon’s peculiar orbit and some of its other properties. But, as Bob Jones University astronomy professor Ron Samec noted, recent studies refute even this origins scenario.
Primarily we’re talking here about the “[giant] impact hypothesis” – which is not “new,” being first proposed in 1975 – but Thomas quickly veers off into older, more obviously false theories. Continue reading
