If you’d bother to do a bit of research, you might find that a good percentage of those phenomena do in fact have scientific explanations and that many of the “mysteries” are only mysterious to those who can’t be bothered to educate themselves. Science makes no claims of omniscience. We don’t know everything, and probably never will, but the answers to many of your questions are there to be found. Science, however, can only light a candle. It can’t force you to look at what the light reveals. If you choose to remain ignorant, that’s entirely your decision. Just don’t be proud of it.
