What if Aliens really Exist??

Do aliens exist? This is a really interesting question and one that NASA has been trying to understand, explore, and figure out for a long time. We have not yet discovered life on any other planet, and we have not seen any scientifically supported evidence for extraterrestrial life.

But if we think about life on this planet, beyond the big things — the elephants, the whales, redwoods trees –– and focus on the tiny things, nearly everywhere on Earth that we’ve looked, we’ve found microbial life.
