Quote: "The only way to tilt the Earth would be a direct collision by something pretty massive. I might calculate this tonight for fun but my guesstimate right now is the colliding object would have to be at least as massive as Mars."
Comment: I wondered when someone would finally catch on. Congratulations, Eta, you "guesstimate" regarding Mars is very nearly right on the money!
What actually happened is that Venus was originally in an oblique orbit that took it inside of and outside of our solar system kind of like a comet. On one of it's trips through our system, it came a little too close to Jupiter and had all of its water sucked out of it's frozen atmosphere. This huge mass of carooming ice collided with Mars, instantly melted on account of the heat created by the collision, combined with the water then existent on Mars, but because of the diminutive size of Mars, and due to Mars's relatively low gravitational pull, this huge mass of water continued right on its erratic path through space. Next stop Earth!
Well, as this huge mass of intersolarsystemic water approached Earth, it collided with the Moon which just happened to be about the same mass as this water cloud. The Moon was pushed toward and collided with Earth in advance of the water cloud. The Moon veered off back into space much as a billiard ball would, and miraculously (due to some divine English spin applied by old Genesis Fats himself) came to rest back in its previous orbit. The lunar collision created a huge indentation on one side of the Earth that the water cloud immediately filled and over-topped. The over-topping wave action caused Noah's Flood, and subsequent erosion and sedimentation filled in the indentation left by the Moon.
Venus came to rest in its present position between Mecury and Earth, and after a year or so of flooding, the excess alien space water evaporated from Earth and back into space due to its anti-gravitational isotopes.
