I guarantee that there is extraterrestrial life out there... There are far too many stars in the cosmos percentagewise to prevent the arising of other intelligent life on other worlds... We've already seen proof that life has existed in bacterial form from the Mars Asteriod... The odds of Earth being the ONLY planet to be able to support life in the universe is so infitesimally small as to be non-existant.
