2 Peter 3:8 (New International Version)
8 But 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.
Psalm 90:4 (New International Version)
4 For a thousand years in your sight
are like a day that has just gone by,
or like a watch in the night.
I have no problem with God creating the universe in six days, six thousand years or more. What is important to me is that I believe in the Creator, not coincidence. Einstein put is one way, "Coincidence is God's way of remaining anonymous" or you could be more hard-core like Paul
Romans 1:20 (New International Version)
20 For since the creation of the world God's invisible qualities—his eternal power and divine nature—have been clearly seen, being understood from what has been made, so that men are without excuse.
Anyhow, I'd better keep on topic myself ;)
All the best,
Stephen
