In Isaiah 45:18, God said He created this earth to be inhabited, i.e., lived upon, and it will be that way in His future Kingdom here on earth also. The meek shall inherit the earth, as written.
In Isaiah, He also tells us we will build houses and plant vineyards, and no one will claim or steal our labors.
We all will have the "spiritual body" type Apostle Paul taught about the resurrection in 1 Cor.15. It is a body type that will not die, nor get sick, nor feel hot or cold, and it will be able to live upon this earth. It won't pollute this earth either, which because of our flesh requirements today that does cause man to pollute the earth.
The whole earth will be one huge Paradise, even temperatures across the whole globe. The oceans and seas will no longer exist, with those waters going back up in the atmosphere to fill all the holes in it, forming a protective canopy over the whole earth. Dew will water much of the earth, so no more violent storms.
The Father Himself will dwell with us, upon this earth. His River of the waters of life will flow out of His Paradise (Eden) to all other waters on earth which will be healed with many fish (see Gen.2).
Those saved will have right to the tree of life, it bearing its fruits per its months with its fruit never being depleted all year.
Man's concept of time will be no longer.
