Was life introduced to Earth ?

GeraldtheGnome: Creation theories about even one god or goddess had created life from nothing and/or from spontaneous generation is false. No one also will ever be able to prove or disprove that abiogenesis has ever occurred. Has anyone thought of any other alternative such as was life introduced to Earth ?

kittybobo34: That is called Panspermia, and it is just as likely. Recently they have found organic chemicals in meteors, as well as a micro fossil in a Mars rock although there is debate as to whether the fossil is real or or a natural fissure.
