2 Peter 3:5-6

5 For when they maintain this, it escapes their notice that by the word of God the heavens existed long ago and the earth was formed out of water and by water, 6 through which the world at that time was destroyed, being flooded with water.

Here Peter points out the flaw in their thinking—that all things in nature continues as it has from the beginning of creation (v.4) by an evolutionary process. He points out two explosive events in world history that were nothing like what they were suggesting.

1. That the world was created instantaneously (and perhaps explosively) by God’s voice in 6 days.

2. That the world was later destroy (because of man’s sin) quickly and destructively by water.

Again, these events came to the earth not by any long evolutionary process, but suddenly by the word of God. And in this same way He will come and bring His judgment.
