Skeptics don't need real evidence because they already know what all the answers are supposed to be.
All they have to do is hear someone suggest something like Atlantis and they automatically know that it is a natural formation because Atlantis couldn't have existed.
Just like astronomers used to know with certainty that rocks didn't fall from the sky because there are no rocks in the sky. So anyone who claimed to see a rock fall from the sky was obviously a liar or crazy.
VERY well put.
