Since Jesus' second coming is before the thousand years, then Peter's ending is a thousand years after His second coming.
Peter only speaks of the end of this world, not about anything before it.
Did you even read my post? You quoted just one sentence from it and didn't address anything else I said. Why not? You say Peter only speaks of the end of this world, which you say is 1,000+ years after Christ's return. Then please explain why he said what he did in verses 11 and 12 here:
2 Peter 3:10 But the day of the Lord will come like a thief. The heavens will disappear with a roar; the elements will be destroyed by fire, and the earth and everything done in it will be laid bare. 11
Since everything will be destroyed in this way, what kind of people ought you to be? You ought to live holy and godly lives 12 as you look forward to the day of God and speed its coming. That day will bring about the destruction of the heavens by fire, and the elements will melt in the heat. 13 But in keeping with his promise we are looking forward to a new heaven and a new earth, where righteousness dwells.
Peter was addressing his readers in the first century along with anyone else who would read it after that. Agree? And he told his readers that they "ought to live holy and godly lives as you look forward to the day of God and speed its coming". Why would he say this to his readers, including you and me, if the fiery destruction he described can't possibly happen in our lifetimes? In your view, the only ones who would need to concern themselves with living holy and godly lives as they "look forward to the day of God and speed its coming" would be people who are alive 1,000+ years after Christ's return.
So, you are basically saying that all of those who read Peter's warning up until Christ's return and 1,000 years afterward have no need to heed his warning about living holy and godly lives while waiting for the day of the Lord to come since it can't possibly apply to anyone until 1,000+ years after His return. Yet, that is not the impression Peter is giving in that passage at all. Instead, he gives the impression that all believers who read his words there should heed his warning about living holy and godly lives while looking forward to the day of the Lord. And the reason why that is the case is because it has been possible for the day of the Lord to arrive ever since he wrote those words since no one knows when that day will come.
Also, in verse 13, Peter said that we look forward to a new heaven and new earth in accordance with the fulfillment of "his promise", which is the promise of His second coming (see 2 Peter 3:3-4). But, you and other Premils are looking forward to an earthly millennial kingdom in accordance with the fulfillment of the promise of His second coming instead.
