It is difficult because a few words are not adequate to express such complex ideas. In general, my understanding is that faith is a belief based upon things not seen or experienced. That is why I say "beyond" belief. There is a grey murky area, i.e. I've never had a rhino horn to the gut but I've been hit in the gut before and I can clearly ascertain that something hitting me there that is sharper and with more force than the things that have gotten me in the gut would be a far worse experience. I have no experience on which to make conjecture about afterlife except a willing faithfulness. And now you've introduced prediction into the mix.
You should kill yourself, RoxSqaud! Then come back and tell us! Whether it was written on a book or if your mom, grandma, or friend told you, you should always strive to be a good person. I feel like religions have the same basic common sense rules, but they differ in lots more things like DEATH and what happens after your life completes existing. Still, I agree. You don't need the holy books to tell you to be good. Just be good.
I'm a Christian but I'm no fundamentalist. My favorite thing to bring up from time to time is to ponder aloud how those Christians most closely descended from Jesus lived without a Bible. They did it for some 200+ years-- on oral tradition alone. Christians today seem to want to not be able to function with a Bible. It's a great book, no doubt, but it is neither the beginning or ending place of my faith.
There are many who claim to recall parts of their past lives including some in my own family. None of that though would qualify as scientific proof that cannot be explained by other means. To cut to the chase if you are asking if there is any empirical proof of reincarnation to my knowledge there is none. If you are going to ask why this belief came about in the first place or why I believe it that is a different question which I will be glad to explain but it will take some Buddhist philosophy to explain.
The first step to understanding "afterlife" is proving that the soul exists. If we can't prove the concept of a soul, then all of these theories cannot be proven either. Seems like this is harder to prove than the existence of UFOs. From a scientific standpoint, all the things that are tied to the soul can be explained to be an effect of the mind. Often people use free will as a justification for the existence of the soul, but free will can even be explained through neuroscience. I just think the brain controls our actions, emotions, ect and not the soul. People can't even agree when a baby first develops a soul, and they're arguments are all out of their asses. Thats why issues abortion debates are so stupid....but I'm way off topic. :grin:
My answer is NSFW kinda. Spoiler When you die, you turn into a sperm and an egg. The sperm and egg shoots into their respective bodies through reverse-ejaculation...baby is conceived.
