Ok so I'm not sure how many parts of the country are getting it but the My Pillow guy is hawking his book. In the commercial he talks about using math to "prove" god exists. What do people say? These are the first two things that popped up on google.
For the second video, I would respond with “I do not know” to the question of why math/physics is consistent. It’s a perfectly honest response and shuts down the argument as the questioner must then propose a reason and defend it instead of you defending your position.
Further, I may want to disagree with the premise that mathematics is consistent by citing Gödel’s Incompleteness Theorems. I could also show that physics is inconsistent given the contradiction of Quantum mechanics and General Relativity.
Though I may hold off on mentioning those things until the person absolutely paints themselves into a corner by relying on that premise.
His premise is off the mark, from the start. Just because there are multiple consistencies in the world, does not mean that they were put in place by some god-thing. If there were not consistencies in physics, etc. THIS universe would either not exist (my guess), or be of some other sort, and never have made life as we know it, which is dependent, if you will, on physical and chemical consistencies. People's agendas blind them to things that do not fit said agendas.
Here's a much simpler mathematical explanation. Religions and gods were all created, with 100% certainty, no probabilities here but 100% certainty, by feeble human minds that had no basic knowledge of how natural things exist. Thus all were man made, ergo product of human uneducated minds. In consequence, all a figment of feeble minds. You're welcome.
Let's put aside for the moment that the whole point of The Theory Of Evolution is to provide a plausible account of how living organisms can move from the simple to the mind-boggling, seemingly non-intuitively complex. Even if a god or gods did it, it does not follow that the Bible, or Christianity, or any other religion has any validity. You still wind up in the same place, not worshiping any deity, any having to devise your own values.
