Elaborating on the Questions

Since some of you are wondering what exactly my questions were referring to, I will elaborate.
1. What is heaven really like?
What I mean by that is - How can some people say Heaven is pearly gates and gold walkways or whatever you'd prefer. Others have no idea. How can we have faith that Heaven is a place to look forward to?
2. Is there really a Heaven or a Hell?
What I was referring to was - How can we have faith that a Heaven and a Hell does exsist?
3. Where do all of our different forms of faith come from?
What I meant by that is - Where do other religions (besides Christianity) come from? Is it some random idea that someone had or did a miracle happen to make them believe in something other than Christianity?
4. Why does everyone have a desire in the supernatural?
Meaning - Why do we all (human-beings) have a desire to see things that are not seen on a daily basis. Such as, ghosts, demons, angels, etc.
5. Where do some ideas of the supernatural come from?
Elaborating - Where did people get the idea of a ghost or any creature that is rarely, if ever, seen?
Did they actually see one or do they just make up stories and we (as human beings) are that gullable to believe?
Anyways.. I hope that helped. Let me know what your answers are!
