http://personalgrowthcourses.net/video/ufo_videos [Edit by Ivan: link updated] Bearing in mind this post by Ivan in the UFO stickied thread. 10,000,000,000,000,000,000,000 stars in the universe, a very conservative estimate but let's assume it's correct. And the Drake equation is possible given the criteria and confirms there must be intelligent life: maybe in the galaxy, but definitely in the universe by the laws of probability. http://www.activemind.com/Mysterious/Topics/SETI/drake_equation.html And apply this to the universe, in a sort of what if way assuming this is fairly typical. My question is two fold, we're fairly certain that probability indicates there must be life elsewhere in the universe, and assuming evolution works in simiilar if not the same ways elsewhere: it's fair to claim that their is intelligent life, so we accept life is out there? Yes/no? Now given the conclusion is yes, do you think the intelligent life has visited Earth?
