Well I may not have personally seen hell or heaven but I know some folks who have. Their experience is worth something. Even if it is anecdotal that doesn’t mean it isn’t real. I could tell you some short stories about a recent trip to Argentina. Just because it is anecdotal doesn’t negate the trip nor what I experienced. You can put your trust in science but science has been wrong many times...many times. Science in no way means it is always correct nor is it infallible just because it is science. Supernatural doesn’t negate existence. Invisibility and undetectability by current means does not negate existence either.
An experience, an anecdote, a trip, a story. Things occurring naturally, not supernatural things. Heaven and Hell are supernatural assumptions. Assuming the supernatural, does not mean the supernatural could exist. It cannot just be assumed into existence. Science is so successful exactly because the method it uses tries to prove its findings wrong. Actually, it does. Supernatural is supposed to be something beyond existence. Beyond existence is not existence. Not existence, then it doesn't have existence. Doesn't have existence, then doesn't exist. Hell is said to be beyond existence so cannot exist. So when you no longer exist you're supposed to exist in a place that has no existence. Ironically enough, supernatural is a natural belief phenomenon, so not even supernatural of itself.
If there were an afterlife and with there being no rational or reasonable information available about it beforehand, likely your bet is exactly the right one that would win the prize.
There are plenty of things in the universe that have definition and which plainly don't exist. Heaven is only defined by hearsay. You might accept hearsay, I don't. The level of detail in the hearsay and the number of people who accept it doesn't change the fact its still hearsay.
