Here is why it is important to understand a debate about the new vs the old heaven and earth, when teaching the millennialism of Christ on earth.
For most people, there is no debate, but one has been made in order to justify doing away with Christ coming to judge and rule the natural people of the earth: the earthly kingdom of Christ over natural people. When the risen Lord is also King, Ruler, and Judge over all people on earth.
There are two certain prophecies, that requires the Lord to stand on the earth in Person, in order to keep His promise and fulfill prophecy of Scripture.
1. In Gen 13, God promises to give Abraham himself, the land he walked on this earth.
2. Job prophesied in Ch 19, that he will see His Redeemer and God on the earth with his own eyes.
That requires the Lord to be standing on the earth with the resurrected Job seeing Him, as well as the Lord having power over any and all land of this earth, to freely give to Abraham as promised: there is no rule of man nor power of Satan on earth to resist Him. That is what is promised on earth after His second coming.
To reject this, one must either disannull or change the promise and the prophecy.
Anti-earthly kingdom millennialists try to do so, by several devices: Disannulling the promise with the OT, Spiritually fulfilling it in the NT, Leaping over the old to the new earth, or Making the old earth into the new earth, by way of renewal.
The last one is the only one with any possible merit, if it is true.
