I forgot to add this part. When taken in context that verse means nothing what intelligent design people want it to. Simply put, Peter is calling for patience. We humans have no patience and our timetables and desires are not the same as Gods. Please read:
2 Peter 3
The Day of the Lord
1Dear friends, this is now my second letter to you. I have written both of them as reminders to stimulate you to wholesome thinking. 2I want you to recall the words spoken in the past by the holy prophets and the command given by our Lord and Savior through your apostles.
3First of all, you must understand that in the last days scoffers will come, scoffing and following their own evil desires. 4They will say, “Where is this ‘coming’ he promised? Ever since our fathers died, everything goes on as it has since the beginning of creation.” 5But they deliberately forget that long ago by God’s word the heavens existed and the earth was formed out of water and by water. 6By these waters also the world of that time was deluged and destroyed. 7By the same word the present heavens and earth are reserved for fire, being kept for the day of judgment and destruction of ungodly men.
8But do not forget this one thing, dear friends: With the Lord a day is like a thousand years, and a thousand years are like a day. 9The Lord is not slow in keeping his promise, as some understand slowness. He is patient with you, not wanting anyone to perish, but everyone to come to repentance.
