FYI, I edited potentially disrespectful descriptions of belief systems in this answer. While sharing your perspective, it's important to remember that others hold different belief systems. Let's aim for respectful dialogue, even when we disagree.

qohelet‭You are missing part of the point. What makes getting preached at about these belief systems so annoying is in part that they are made-up, and that they are structured in such a way to make testing their fundamental hypotheses impossible.

For example, I have several times encountered someone praying for a particular outcome, and when that outcome was realized, they presented that as "proof" that praying worked. Clearly, that's logical fallacy. However, such people seem to be largely immune to facts and logic.

Thanks for clarifying, Olin. My intention here was to prevent any misunderstanding that you were implying any specific Christian (or non-Christian) beliefs are "silly made-up belief system[s]". However, this question itself is not constructive and calls for subjective speculation, so is going to be closed anyways.

qohelet‭ I was, although I admit "silly" is arbitrary and emotional and I shouldn't have said that. However, "made-up" certainly does apply. When something has no basis in measurable fact nor presents any testable hypotheses, "made-up" is a fair description.
