Earth is the planet with the most life. Some people believe we are aliens and evolve from a creature called archea. Archea can breath iron and can survive extreme temperatures. They can go for millions of years without food, and live in the hot springs of Yellowstone National Park. Their characteristics do make it possible that if the came from another planet that was destroyed, they could have been inside of a meteor for millions of years and crashed on Earth (archea is microscopic).
The Mars Rover also discovered water on Mars. To survive, creatures must have a water sources. If there were aliens on mars, they would have to be microscopic.
