do you think that new sistem will be on earth or in the sky?

I think you mean the destruction of creation and the creation of the new world, right? As it goes, there will be both a new Heaven AND a new Earth. Both will be unmade and then made again. The City of God will be on the New Earth.

Your discussion topic is very vague. I am not religious but wouldn't you think that is the heaven was the sky we would be able to reach it or see it as astronauts exit our atmosphere? Do you mean heaven is the voids in space that are made up of nothingness? New system like? World order?

I believe that when we die, we will become like spirits and live in the universe as God does. I don't believe there is actual place in the sky, called heaven. As God is all around us, I believe we too will be all around . When Christ comes again, I then believe we will receive our bodies again,and no longer be a spirit, and the new Heaven will be on earth...peaceful, happy, joyful, no sickness, no getting old, etc.
