All ready to hit the Comet Sweat

[DandyDon]

Maybe objects the size of Pluto in addition to comets (and other Kuiper belt objects) collided with Earth... we could be made up of comet sweat and left over stellar parts. Earth maybe the dumping ground of the cosmos.

I'd say no maybe about it, Earth is one of them sure. There was one planetoid that did hit, causing the Earth to lose enough lava type material to produce our one moon. Evidence suggests several other asteroid type hits, like the one blamed for killing off most life including the dinosaurs, and there may well have been others that hit so long ago that there is no evidence.
