If you look up in any direction you'll see them. Bastard clouds.

Should really have been in the Death Notices thread.

Anyway it is interesting to hear that planet earth started life with no water, which is required to sustain life. Scientists suggest we got water from a comet. Therefore life as we know it was created by a comet.

Worryingly though, it could also be destroyed by a comet. So lets just go out and party. Ladies, drop me a pm.

Explain this one to me. If an asteroid hit the earth with even a couple of 1000 tons of water where did the rest come from. Are they saying that every last drop of water on this planet came from asteroids or did the water just multiply to fill the oceans.

I presume that back in the early days of the Solar System the skies were littered with comets. There was a lot of material out there and the Sun's gravity was pulling things into its orbit which in turn were forming into planets, moons, asteroids and comets. So impacts from comets might have been a frequent event, and a lot of them would have been a lot bigger than a few thousand tons.
