This is the most lengthy thread I have ever read since I joined Bitcointalk. You have done justice by analyzing the two most popular religious believe. I personally will not belong to any of those religion if it was only through just reading or listening to the religious leaders teach. I am a Christian, I stick to being a Christian because of my personal enchanters I have with Jesus and the Holy Spirit. I have received healing severally without taking any drugs. The holy spirit guides me by showing me visions of what will happen in the future and they all come to pass.
So, fill yourself on the Bible. It's the only accurate source for Christianity. See you in Heaven.
Where is Heaven?
Is that some sort of comic book convention?
Most mythologies (also known as religions) offer something in exchange for following a number of precepts. Most of the organised religions basically try to achieve a certain social order and peace in a society. It is much easier to do so if you promise a price for good behaviour and what is better than eternal life in a paradise, heaven or whatever you choose.
There is no obvious reason to believe in any of the "religions" than there would be to believe in the ancient Greek gods or in the sanctity of cows. There is no obvious reason either to think that there is nothing out there, whatever shape may it take, that has some connection with eternity or our creation. If something is certain, is uncertainty on the fundamental questions of life.
