I’m not an atheist but an intelligent atheist would laugh at what you wrote, asking someone to prove a negative is not winning the argument, it is giving up! I say there are tiny invisible fairies less than one millimeter tall having wild parties in your front yard. Prove they’re not. There is a reason why the burden of proof in CIVILIZED courts is on the prosecution. If every accused had to prove he DID NOT commit the crime we would all be in jail.
By the way, some of the greatest thinkers of all time have come to the conclusion that one cannot prove or disprove the existence of God by reason. I tend to agree.
They want us to prove a positive. What’s wrong with asking them to prove there is no G-d? They state they don’t believe in G-d, so, give me your reasons.
