Alien Life: Top 10 Places To Find

Are We Alone, Really? The race to find intelligent life, or any life at all, beyond Earth has been a heated space scramble for decades. Even though no concrete evidence of extraterrestrials has ever been confirmed, it seems like every space probe ever launched and scheduled to launch has a "FIND LIFE" stamped in its mission.
