I am hungry. I decide to make myself a sandwich, with peanut butter, and one of the following:
strawberry jam
honey
grape jelly
None of these are evil, yet they are choices.
If I throw a jar of strawberry jam at your head, is that not an evil choice? You chose to make a sandwich with that jam, but someone else can choose to do something evil in the same situation.
Those problems do not prove math and science to be false, as they do not challenge fundamental assumptions.
If you're saying that it's only because you don't really understand them. Mathematics was widely assumed to be complete, consistent, and decidable and then Alan Turing's Halting Problem came along and blew that out of the water. So it's been mathematically proven that not everything in mathematics is provable. Seems paradoxical to me! I guess that means the field of mathematics is just a weird superstition we should mock, right?
