What theory suggests that life originated from organic compounds from outer space?

The theory that life originated from organic compounds from outer space is known as Panspermia. This hypothesis posits that life, or at least the building blocks of life, were delivered to Earth through comets, meteorites, or interstellar dust. Panspermia suggests that life might not have originated on Earth itself but rather was seeded from elsewhere in the universe. This idea expands the possibilities of extraterrestrial environments harboring the necessary components for life, leading to the suggestion that life on Earth could have evolved from these external sources.

In contrast, other theories mentioned have different implications. Biogenesis refers to the principle that life arises from existing life, proposing that life cannot spontaneously generate from non-living matter. Evolutive Theory typically refers to Darwinian evolution, focusing on the process of natural selection and the development of species over time, rather than the origin of life itself. Spontaneous Generation, an outdated concept, was the belief that living organisms could arise from non-living matter under certain conditions, but this idea has been thoroughly debunked through scientific investigation.
