Scientist are searching for even simplest forms of life in the solar system. This is done by examining meteors, searching in space through carious satellites etc. also new high technology telescopes are searching for extraterrestrial life.

Its been a long time since we humans are searching for someone that is different from us. Every time, we ended up with a little bit of success, receiving another clue of the existence of aliens. but still, their existence is a big question mark for us.
