Do you think extraterrestrial life exists?

Scientific studies show that there are signs of real extra-terrestrial life. Sure, aliens have been in fictional movies, games, etc., but somehow they have become real. For one, I've heard there has once been organic alien life inside of 3 asteroids. This came to be because some water slipped through into the asteroid, waiting to be consumed by the alien bugs. Another thing I've heard about is that in the clouds of Venus, there is bacterial life present. A scientist suggested that there is life on Venus, and, obviously, he/she is right. Venus's clouds also are similar to Earth's conditions, giving out more proof.
