Here's some tips about agnostics from one: Agnostics know that they don't know. That leaves them open to the possibility of everything, including the existence of UFO's. Agnostics may have a higher tendency to believe that life exists elsewhere, because it is probable. They might also assume that they will never meet an alien, because it is improbable. Belief, skepticism and woowoo are oranges to agnosticism's apple, there are plenty of woowoo agnostics. The buddha was the uber-agnostic, and he was totally woowoo.
