It doesn't take long to look at the plethora of ufo sightings on the internet, millions of people over decades have made statements saying they have seen ufos. There are many people who have worked in aviation and military and other organizations who have made statements saying they have seen ufos. The evidence is there, it has been there for years. The evidence is so overwhelming if it was a murder trial the accused would be guilty beyond a shadow of a doubt.

You don't have first hand experience, you have no evidence against it, you have no facts proving they don't exist, you know a guy who was in the military who says they never saw anything, whoopty fucking do, there are millions of people who also have never seen anything. Not seeing something isn't evidence that something isn't there.
