Answer:
Panspermia is the theory that microorganisms or biochemical compounds from outer space are responsible for originating life on Earth and possibly in other parts of the universe where suitable atmospheric conditions exist. It is proposed by Swedish chemist and Nobel laureate Svante Arrhenius.
