The theory that life on earth originated from spores or germs that evolved elsewhere in the uiniverse; -- in contradistinction to the theory that life evolved on earth from inanimate matter. This theory, originally suggested by S. Arrhenius in 1907, is sometimes advanced by those who feel that the time required for evolution of life is too long for life to have evolved on Earth from inanimate matter.
A theory suggesting that life on a given planet may have been seeded by life originating on another planetary body.

Theory that microorganisms floating in space or attached to interstellar dust particles can germinate and start the evolutionary chain of life when they encounter a hospitable sterile planet.
the theory that life exists and is distributed throughout the universe in the form of germs or spores that develop in the right environment
the idea that reproductive bodies of living organisms can exist throughout the Universe and develop wherever the environment is favorable; during the evolution of the Universe, conditions favorable to the development of life are postulated to have prevailed at different locations and at different times; 'seeding Earth with life'.
Panspermia is the hypothesis that "seeds" of life exist already in the Universe, that life on Earth may have originated through these "seeds", and that they may deliver or have delivered life to other habitable bodies.
