A belief in a god is not the problem.

IT does not matter, mainly because it does not exist.

Those rules that you are trying to reinstate are rules made by men who didn't know anything about the earth, nor anything about all of the other inhabitants of it. How can you not see that?

I am speaking to the US Bible thumpers here, of course ~ many of whom are flat-earthers who deny evolution and see scientists as evil people who are constantly trying, and succeeding, in disproving their beliefs one by one.

My religion teacher said that there are no atheists because in order to reject God, you must first have a concept of God, and if you have a concept of God, you are not an atheist. In what way is this true, if at all? Why?

I do not personally care if you believe in a god or not.
