Exogenesis ("outside origin") is a hypothesis that proposes life on Earth was transferred from elsewhere in the Universe. Panspermia is similar but hypothesises that seeds ("sperma") of life are general throughout the Universe.

This is a possible solution to the creationists' first cause: natural rather than god-given origin. However, it merely pushes the problem back one step, for now we must ask where the seeds came from.

Sir Fred Hoyle and Chandra WickramasingheWikipedia's W.svg were supporters of the hypothesis and further contended that lifeforms continue to enter the Earth's atmosphere, and may be responsible for epidemics, new diseases, and the triggers for evolutionary spurts.


Imperial College, London scientists have confirmed for the first time that important components of early genetic material, including uracil and xanthine, found in meteorite fragments are extraterrestrial in origin.
