I believe that we would have evolved seperately, but a shared seeding from cosmic materials isn't entirely unplausible, possibly as a trigger for development.

That said alot of the shows on the History Channel wouldn't exactly stand up to academic scrutiny, and the "experts" on shows are abit questionable.


I believe all life in the entire universe has the same genetic makeup/ building blocks.  The bacteria that seeded the Earth isn't any different than the bacteria that started life on other planets.
