Ghosts and aliens have not been proven to exist or not exist. You can't call bull until it's proven.

about atlantis, first of all it was a city on an island so yes it could be destroyed in one day and one nigth, now i dont say that it is true but you have to know that before they found the remain of pompei its was a legend too and many people believed it did not existed same for troy, and camelot as not been found either dare you say it did not existed. but i concur on alien and ghost and, lol mermaids. but we must realized that there are still many things we do know understand and that are still beyond our comprehension.

Honestly, I think it is a myth that all alien abductees are “Cletus the slack-jawed yokel”. There are a lot of perfectly sane and INTELLIGENT people that have had abduction experiences.

There is a lot of evidence out there pointing toward the existence of UFO's. I have witnessed them firsthand, and if you look online, there are TONS of videos out there. Some might be fake, but there are ones that are well documented and were seen by hundreds, sometimes even thousands of people.

I think it is impossible to shut down the debate when there is a lot of evidence pointing toward the contrary. There is enough evidence to at least keep an open mind to it.
