You don't believe in afterlife i suppose. I can't make you understand. Google for parellal universe and afterlife. I think science made some discovery. After that read the holy Quran. I am not asking you to believe. Just requesting you to read. Reading it won't make you a terrorist (muslim) as western media promotes.
I can tell you that there was no such discovery. To this date, the simplest and therefor the most probable scientific theory is that there is no God and that it is simply a lie made to benefit the few. All the prophets were kings and collected taxes, it is in the Bible, I assume it is in Quran as well where they collect taxes.
Kings and religions always went together.
We have all this knowledge about big bang and that time couldn't exist before that due to special relativity. We know that 95% of things in religious text never happened, like the Noah's ark, or that it never will, like in Revelation where they say that stars will fall from the sky (quite impossible). We know that they never predicted anything correctly, most things about the past are wrong, many predictions are impossible and all of the possible ones only add complications to our current theories.
If you want to believe, then believe. But that is just what it is, believing. You can't logically get to the conclusion that religions are nothing other then a lie, but you can believe whatever you want. Remember that belief isn't logic.
If you wasn't scared into it when you were younger, when you didn't understand already how the world was created from the scientific point of view, then if I told you now something like that, you wouldn't believe me. That is the obvious truth. If I tell you something that seems highly improbable and more complex theory that doesn't explain nothing else that science already does and I had a clear benefit of you believing in it, you would be naive to believe me.
But that is logic. You can believe what you were thought as a child that somehow that was exactly the truth and everyone else who was thought a different story on another part of the world is wrong. Maybe it is, maybe you were born and hit the jackpot and were thought the truth, but know that if you were born somewhere else in another family, you definitively wouldn't.
