PANSPERMIA THEORY

The panspermia theory argues that life is originated in space, in spatial ices, and continuously distributed to the planets by comets and meteorites. Also by space dust, asteroids and planetoids as well as by spacecraft carrying unintended contamination by microorganisms known as directed panspermia. The theory argues that life did not originate on Earth, but instead evolved somewhere else and seeded life as we know it. Molecules needed for the development of life, such as carbon, water and ammonia, have been found to be generated and transported through space. If the basic building blocks of life are able to be produced in space, it would mean that life found elsewhere in the universe would have the same molecular makeup as us.
