@neologist,
You have missed the whole concept.
This earth is going to burn up in hell.
2 Pet 3:10-11
10 But the day of the Lord will come as a thief in the night, in which the heavens will pass away with a great noise, and the elements will melt with fervent heat; both the earth and the works that are in it will be burned up.
11 Therefore, since all these things will be dissolved, what manner of persons ought you to be in holy conduct and godliness,
(NKJ)
