People have long lives, Isaiah 65.20, so earth rapidly repopulated; as before few follow Christ and many reject Him (Mt 7.13-14)
Christ rules on earth (Isaiah 11.10, Zech 14.9 ) ; all nations praise Him, though since there will be many unbelievers, this praise will be in many cases under compulsion, as in Phil 2.10-11.
The compulsion aspect is indicated by the verses that speak of Christ ruling "with a rod (instrument of punishment and correction) of iron": Rev 19.15); and eventually breaking/destroying rebelling nations with that same rod, Ps 2.9 .
Those Christ redeemed will reign on the earth as Christ’s agents. Rev 5.10.
At the end of the Millennium
Satan freed, Rev 20.7.
Satan deceives the nations into rebelling against Christ, God's anointed: Ps 2.1-3 , Rev 20.8.
The nations from all over the earth ("the four corners of the earth", Rev 20.8) assemble to attack Jerusalem, Rev 20.9.
Attacking forces destroyed (Ps 2.9) by fire from Heaven, Rev 20.9.
After the Millennium
The heavens and the earth are annihilated by fire, 2 Pet 3.10-12
God creates a new heavens and new earth, Isaiah 65.17, Isaiah 66.22, 2 Pet 3.13, Rev 21.1
The new creation includes the New Jerusalem, a city approx. 1,500 miles long and wide and 1,500 miles high (probably shaped like a pyramid, though the dimensions would also allow a cube shape) containing only righteousness, peace, and happiness; [Rev 21].2-27.
