Maybe all of those movies about extraterrestrial life aren't so far fetched after all. Check this out:

If you were to lazy to watch that, I've got you covered. NASA scientist Richard Hoover has discovered a type of bacteria he calls "extremophiles." They're named for the extreme climates that they live in, makes sense. His research has raised questions about life on other planets. Does it exist? Have there been life forms on other planets? Hoover cracked open a meterorite which hit the earth in hopes of finding bacteria inside. He did and these “extremopiles” appear to be older than the Earth. This seems to mean that there may have been origins of life other than Earth. Comets can house bacteria which can then find new homes when the comets collide with planets.
Maybe life does exist outside of our planet Earth?
Men love to wonder, and that is the seed of science. - Ralph Waldo Emerson
