I’m distrustful of the collision hypothesis. It reeks of the silly theories of Velikovsky who tried to explain the miraculous events of the Old Testament in terms of a series of encounters between earth and a runaway planet that eventually became Venus. And so far I’ve not seen the advocates of the collision hypothesis even try to explain where such a planet came from or where it went. Too pat, too ad hoc, too little evidence, though I am open to any good explanation of why the moon is so disproportionately large.
