So you just want to know about the Christian version of heaven. You're not interested in the beliefs of other religions. Well, sad to say that if a lot of other people are correct Christianity is a false religion and all Christians are going to hell. Do you really want to take that chance?

 why should i bother preaching about how wonderful atheism is when you can just read the god delusion as so many others have mentioned?

go look up the celestial teapot if you want a theory so desperately.

This is a debate that will take several decades to conclude. Beliefs erode over time as science stars explaining thing that were unknown before. So far there are still beliefs that linger because scince has not yet provided a definite answer but eventually it will. As far as consciousness, it is the effect from the ability to reason in order to solve problems that enable us to survive which took time to evolve as our brains became larger. Recent studies with chimps show that they have a primative understanding of right and wrong (just recently saw a documentary in PBS) anyways the experiment involved another chimp stealing food and the other chimps punished him, so there goes our uniqueness in that field. Like I said over time all these current beliefs will fade, but it will take a long time and until then this debate will continue.

no religious text other then the ten commandments come from god, the rest are what man thinks god wants him to say

Imagine there's no heaven
It's easy if you try
No hell below us
Above us only sky
Imagine all the people
Living for today

Belief in God (regardless of what you label yourself or your religion) and be a good moral person.

 I would include the sermon from the mount as something god would be likely to say. But that's just me. The rest of it I consider bad literature at best, pure propoganda at worst.

Deuteronomy 13 and Second Chronicles 15.

^its still been copied from the hand of man

 Have you ever studied the Bible and it's claims?  There are over 700 prophecies in the Bible and 300 of those have already come true.  It is banking its validity on the remaining 400 which no other book in any other religion would dare do.  The chance of 300 of those all coming coming true with mulitple authors over a spand of many years is mathematically impossible.  I do not care if people attack me on my faith, that is their problem not mine.  If anything it makes me sad to see so many people blinded to the truth.  The Bible is not a mere book and if you try to prove that it is, you will see that it is not.
