life didn't come from outer space.
I've never seen anything that indicates that life came from "outer space". Scientists feel that the chemicals, the materials which eventually started or became life were formed or produced in the vastness of the universe.
Some believe that it wasn't exactly that life itself came from outer space, but another part of the building block necessary for life may have come from outer space, combining itself with other building blocks needed to create life that were already here on earth.
The Ancient Ones who came from beyond space and before time.
Life will eventually happen if the required chemicals are present, and have access to each other, within the required temperature range. It is a primordial soup mix.
