"I don't want to believe. I want to know."

"I don't want to believe. I want to know."

"Extraordinary claims require extraordinary evidence."

"Somewhere, something incredible is waiting to be known."

"I consider it an extremely dangerous doctrine, because the more likely we are to assume that the solution comes from the outside, the less likely we are to solve our problems ourselves."
