Could We Be Aliens?

A new video by Time magazine showes how life on earth could have developed by 'Panspermia - the idea that biological material or even living organisims could have immigrated from one planet to another, essentially seeding their new planet with life from afar'.

Some of the basic element needed to create life can go dormant, or dehydrate for the period of space travel aboard a meteor, who could sometimes even function as sort of an incubator, keeping these elements from radiation, cold temperatures and other extreme space conditions.

It would be much simpler for our extraterrestrial friends to put these elements aboard their mother ship and just show up and plant life here on earth, but that's only if you ask me ;) Anyway, interesting stuff.
