Well to be perfectly honest I don't think I'm going to convince you and have no need to do so. But by the same token I have never been convinced to not believe nor do I need to be. But the fact that more people on Earth believe in such things than don't belive makes it more than just "useless"This makes no sense. Science is asking simply for proof that something exists. You are now saying "I can't prove this exists, but you should accept it anyway." So no, we cannot accept that certain things can't have the same type of evidence we're familiar with unless you start giving us good reasons to do so. So far, your evidence consists of pointing out that some people think reincarnation happens. This is useless.
