A cynic might suggest the theory might exist because nobody could figure out how life got started on its own on earth.

The thing is I've never found the asteroid theory particularly satisfying either because it simply inserts another abstraction layer, explaining the problem away rather than explaining it.

That's not to say it's wrong but, in its current incarnation, it's just a bit meh.

I suppose perhaps that's part and parcel of it being a very hard problem to solve.
