Is that how you dismiss everything of no value to back up your own opinion?
I remember one time one gave me the argument that Plato was 'high' and that he invented that story through 'tripping' . The guy was also a historian. I expected a better argument than that. From both you and him .
I'm not sure they owe you an arguement at all. There is not any evidence of Atlantis being real. The burdon of proof is on the believers.
