What is directed panspermia ?
It is a hypothesis that claims seeds of life may have been intentionally spread by advanced extraterrestrial civilization. This was a proposal by Professor Francis Crick and Leslie Orgel.
Basically that aliens planted the seeds of life here on earth. It solves nothing, because those aliens would have needed to come from somewhere. Infinite regress, woo!
You have GOT to watch *Ancient Aliens* on the History Channel! :-)
