Alright folks, it's time to bring up the inevitable... do aliens exist? what are you're justifications, and lets all try to use out those truth tests. Now there is a lot of evidence on both sides saying yes or no, a simple visit to youtube will give you all the info you need to make an educated guess.
Now as for me, I guess I fell that there has to be something else out there with some intelligence. It would be unlikely for there not to be. How could it be that in the BILLIONS and billions of planets in the universe that our planet was the only one to sustain life, it just dosen't work.
