Detailed explanation-1: -This theory proposed that life developed elsewhere in the universe and then arrived on earth. Microbial spores from space were supposedly brought to earth by asteroids or meteors; which jump-started life on earth. However, this theory states how life spread, not how life began.
Detailed explanation-2: -The panspermia theory argues that life is originated in space, in spatial ices, and continuously distributed to the planets by comets and meteorites.
Detailed explanation-3: -Panspermia proposes (for example) that microscopic lifeforms which can survive the effects of space (such as extremophiles) can become trapped in debris ejected into space after collisions between planets and small Solar System bodies that harbor life.
Detailed explanation-4: -noun Biology. the theory that life exists and is distributed throughout the universe in the form of germs or spores that develop in the right environment.
Detailed explanation-5: -A handful of scientists argue that life didn’t begin on Earth, but elsewhere in the universe, and that it … was carried here on meteoroids and other space bodies. The origin could be somewhere nearby, like Mars, or light years away. The idea is called “panspermia”.
