Here are the problems with your rebuttal.
- You're ignoring the appeal to belief fallacy. This isn't some pesky technicality which you can brush off. It is a critical flaw in your reasoning which you must account for. Simply restating your initial assertions doesn't cut it. I get that you want this thread to be about the existence of god. Unfortunately, lots of people believing there is a god doesn't count as a form of evidence... no matter how hard you stamp your feet. Which leads us to your next problem.
- You're shifting the burden of proof. If you believe that god exists, then it's your responsibility to provide evidence. Not mine.
- You may want to review basic geometry to fully comprehend the shape of our planet. Things that are round and flat are called circles. Do you believe the planet is a circle?
We'd both agree that the statement, "Hundreds of thousands of Scientologists believe Xenu literally existed. Therefor, there must be some evidence for Scientology" is laughably false. Why aren't you willing to apply that same intellectual honesty to your own argument?
