Organic molecules is commonly found in meteorites, and comets. Organic molecules is mainly chemistry, but it still is a huge part of the material for known life, cause have we seen, all life on earth has it, so it's like the basis for all known life. What organic molecules being found in meteorites, and comets shows is that this material that's the basis for all known life is universal, further proving the fact that the universe is a bit more chemically life friendly with this material being present. thus, increasing the possibility of life being elsewhere(somewhere else in the universe, outside the solar system). please repost it on r/aliens. you got my permission to do so. I don't have enough karma to post it on there submitted by /u/Y68g4dw [link] [comments]
