Second Peter 3 is about the End Times. A close study of verses 3 through 13 reveals God's plan for the ages. First of all, you must understand that in the last days scoffers will come, scoffing and following their own evil desires. Ever since our fathers died, everything goes on as it has since the beginning of creation. God remains dead.
Evolution is preached in our schools and creation is denied.
But they deliberately forget that long ago by God's word the heavens existed and the earth was formed out of water and by water. God began his plan by destroying the earth by water. By the same word the present heavens and earth are reserved for fire, being kept for the day of judgment and destruction of ungodly men. The plan will finish with the destruction of the world by fire. The Lord is not slow in keeping his promise, as some understand slowness.
