The After Life

It most likely doesn't exist because there is no evidence in any way supporting an afterlife in the scientific world. Even if you see a ghost, who's to say that it's human.
But lets just assume for the moment that there is an after life. If you died and were somehow still aware of your surroundings you still would not be able to interact with any part of the physical universe in any meaningful way, as proven by the fact that we as humans rely on solid unchanging laws of physics just to be able to live daily life.
If ghost tampered in our lives in any way then we would not be able to perform critical parts of life reliably. We rely on unchanging and predictable conditions in order to perform all tests that use the scientific method. We have extremely precise measurements that need to be accurate and reliable in order to understand the universe around us, and we need to repeat those tests reliably in order to convince other scientists of actual discoveries about physical laws.
Now it may be that spirits from the after life are able to interfere with things that are totally unpredictable such as the weather or gambling. But this could all be a need for the human brain to explain things as happening based on some "intent" from some sort of super being, or things are all based on a plan of some kind.
Well it reminds me of a story where somebody had the insane notion that there were religious demons out there to get us and if you said come here demons, then they would come and get that person, so my dad responded to the lady by yelling"Hey demons come and get us, we're ready for you to come out." Needless to say the demons never showed up. But don't you think that if there were evil demons in our lives, that they would be interfering with our scientific experiments. The only reason that bad things happen, or that there are problems in our lives is because we create those problems. If you build a house that is of fireproof material and you storm proof it and don't live in a flood risk area, and you bug spray the property, and you don't live in tornado alley, and you have a lightning rod and what ever else, then you will never have those problems. And by the way you've already protected yourself from most of the plagues that are at the bibles supposed end of the world.
But all that said it's most likely that gambling is 50/50 chance and that weather is based on "cause and effect". So if you are dead and you are still self aware, that leaves absolutely nothing that you can interact with in the physical universe. So when you do die some day don't look forward to it because even if you can travel across the universe, all that you'll be able to do is watch, and you will have no way of ever actually interacting with the universe again for the rest of eternity. Now that's not my idea of fun, unless there's some sort of afterlife version of prozac.
