Seven, I kinda think you lost this battle of wits to Vinman here. The burden of evidence is in the proof, not in the disproving, because the former is possible and the latter is ridiculously impossible. The best investigative minds in the world cannot even disprove that Santa Claus exists.
So as a logical argument, the lack-of-evidence-to-disprove line of thinking is complete vapor. It's a red herring that has zero inherent value in its statement. Your argument may as well have been, "I like chocolate!" It would have carried the same critical weight.
