It is actually possible alien life has come to Earth already! There are some interesting theories that say that meteorites that crashed into the young Earth billions of years ago could have carried organic molecules that might have contributed for life on Earth appearing. However, these are only theories, but we do know that some meteorites do carry simple organic molecules on them, so we never know…
