Problem is, theists don’t understand fallacies. You have to baby walk them through each fallacy. You can’t just say, 'That’s ‘Circular Logic’ or, 'That’s a strawman." They will not have a clue as to what you are talking about. You have to know the fallacies well engough to explain them to a 5 year old.
Sheldon, has the best argument on the site and he uses the same one every single time. It’s not that he is incapable of following the theists down their rabbit holes, he certainly has the ability; however, in most cases he just does not bother. Occasionally he will let his wit play and tie a theist in knots but generally he just does one thing. He asks a question: “What objectively verifiable evidence do you have for the existence of God?” He knows full well that there is no objective or verifiable evidence. ‘God’ is an unfalsifiable claim. As long as you know that the next words out of the theists mouth are lies, you are always on solid ground. It does not matter where they go.
Evolution: Evolution has nothing to do with God or Atheism. If evolution is 100% wrong, you still have no evidence for your god claim.
The Bible: The bible is the claim, not the evidence. It’s a book of old stories with no eye witnesses. (Carful about getting into forgeries and edits you can be asked for evidence and you will be sidetracked into arguing the bible. Don’t do this.) The bible makes claims, it does not provide evidence.
Analogy and argumentation: You don’t need to know anything. You can not argue a god into existence. That would be like arguing a unicorn into existence. You don’t even have to listen to apologetics until you are familiar with them. First Cause Argument; So your saying there is a prime mover, lets just say I give you everything, the universe had a beginning, everything has a cause. How do you get to God? You still have to demonstrate the existence of the god thing. How did you rule out natural causes. How did you rule out Eric the Rainbow farting unicorn… This is a god of the gaps argument. You can put anything in the gap to fill it and still there is no evidence god. God must be demonstrated.
Miracles: None have held against scientific inquiry. In the end, if science can not explain this or that then the proper thing to say is “We don’t know.” and not ‘God done it.’ You still have to show that there is some sort of evidence for the God thing.
It always breaks down to, show me the efidence. Demonstrate the existence of the god thing with clear, objective, verifiable, facts. (It can’t be done.)
All you need do is dig your heels into the dirt and say, ‘Show me your god.’
If you had ever bothered to pay attention to the important articles in “U.F.O. Weekly” (which is published every two months), then you would know that copper actually helps FOCUS the alien radio waves into your brain. Only the molecular structure of tin can disruptively scatter the beams effectively in every-which-way directions away from the brain activity localized in the Paula Abdugotta. Geeez… Get a clue already.
