The Bible is kind of ambiguous on whether this earth will remain or a "new earth" will last forever. I believe that the "Old" Testament scriptures were expecting the earth to remain, simply because their faith was in God and was a simpler faith. 500-1000 years later, believers had a new outlook on the future.
Psalm 78:69 - And he built his sanctuary like high palaces, like the earth which he has established for ever.
Psalm 104:5 - … who laid the foundations of the earth, that it should not be removed for ever.
Ecclesiastes 1:4 - One generation passes away, and another generation comes: but the earth abides for ever.
The Kingdom of Heaven (= Kingdom of God = Heaven) shall last for ever.
Daniel 2:44 - And in the days of these kings shall the God of heaven set up a kingdom, which shall never be destroyed: and the kingdom shall not be left to other people, but it shall break in pieces and consume all these kingdoms, and it shall stand for ever.
Rev. 11:15 - And the seventh angel sounded; and there were great voices in heaven, saying, The KINGDOMS OF THIS WORLD are become the kingdoms of our Lord, and of his Christ; and he shall reign for ever and ever.
Is. 65:17 - For, behold, I create new heavens and a new earth: and the former shall not be remembered, nor come into mind.
Is. 66:22 - For as the new heavens and the new earth, which I will make, shall remain before me, says the LORD, so shall your seed and your name remain.
2 Pet. 3:13 - Nevertheless we, according to his promise, look for new heavens and a new earth, wherein dwelleth righteousness.
Rev. 21:1 - And I saw a new heaven and a new earth: for the first heaven and the first earth were passed away; and there was no more sea.
Whatever happens, God is in charge and it will be for the best.
