"A running hypothesis many scientists hold is that the chemicals for life form inside interstellar clouds. Comets and meteors that form within these clouds contain these molecules. Then, these objects proceed to bombard the planets that form within that solar system during a very turbulent time in its history. These meteors and comets are thus responsible for providing the building blocks for life. Then… it’s all up to the ecosystem of the planet."
