There are people out there that think Heaven is in the clouds, or it dont exist. Everyone has there own opinion though on what to think about God and where they will go after death. Heaven to me is just a place where everything that makes you happy will all come back to you. Your Family, Friends and pets anything that you loved will all be together again, it would be like you never left the ones you loved. As of God I do not think he is a person at all. I believe God is all around us, He is the air, trees, water, plants, he is everything. Just like the planets, we have 8 planets in are Solar System and they are still confirming some. Anyways there are over 170 Solar System so how many planets are in each one of those no one knows. There could even be other life out there. Why would God only want to have life on one planet out of everything he has built. He can do anything he wants and build anywhere, so have you ever thought "what is really on all the planets out there and could one of them really be heaven".
