    But we do see cometary evidence in forming planetary systems.  It's conceivable we could, with better technology, see this happening in another system, or many other systems.

    That may indicate that Earth is by no means special and that there's a decent chance that comets added plenty of water and organic material.  That they've added some is certain, but more than some is in question as the isotopes don't match all that well.

    I'm not saying that life came on a comet--not without a tremendous amount of proof--merely that cometary mass may have helped things along.  How much they may have helped remains to be proven.
