Let's see:
1. FE has it's own math
2. FE has it's own physics
3. FE bunch is religious, fanatically (you can see that from forums, where absolute trolling is allowed by people who accept FE, but any forum rule mistake by RE is banned), since it's inception, by someone with radical religious beliefs
4. FE does not have to prove anything
5. FE does not have any math, physics, biology, geology etc equations, that is any way interconnected - RE equations apply and work together in harmony (anything and everything must be tested, proof provided, accepted by scientific community of millions. FE scientific community with not a single equation, is 3 people?)
Every single RE person comming to this forum is doing it wrong. FE is not about facts, logic, math, physics, testing, proving etc, FE is all about belief.
You do not walk to church and ask priest to prove that there is no god. You just don't.
So why do you come here asking these questions?
You should instead, come and help them prove their point. Why they believe, that earth is flat. It has nothing to do with what you studied in school, it's everything to do with what you hear in church.
