Except they are not the same things at all. #1 numbers and math are a very different domain from hard facts, such as the shape of the earth as humans experience it. In fact, you could probably create a number system, or a mathematics where 2+2=5 (simple example would be a number system the same as we have now, but the symbols for 4 and 5 are swapped). There are interesting ideas to be gained in thinking about what numbers mean, and imply based on questioning that. However, once you’ve accepted all the definitions, and the number system, and the rules of the system you’ve accepted necessarily imply 2+2=4 then insisting that 2+2=5 is nonsensical. That’s the level at which the flat earth era are operating.
