This is a religious question.

There isn't sufficient biblical evidence for heaven being a literal place, in my opinion. However, I do see evidence that the New Jerusalem is going to exist on earth after creation has been restored.

The city of the New Jerusalem described in the Bible cannot be taken literally (i.e. dimensions of the cube-like structure) as this is not how the original author(s) would have understood it. The specifics are derived from Jewish culture, with its focus on numbers and symbols.

By the way, the most prevalent forms of biblical criticism stem from a presuppostion that the Bible cannot mean now what it never meant in the time it was written.
