@PDPrice keeps bringing this up, and it is worth looking at more closely.
“Above all, you must understand that in the last days scoffers will come, scoffing and following their own evil desires. They will say, “Where is this ‘coming’ he promised? Ever since our ancestors died, everything goes on as it has since the beginning of creation.” But they deliberately forget that long ago by God’s word the heavens came into being and the earth was formed out of water and by water. By these waters also the world of that time was deluged and destroyed. By the same word the present heavens and earth are reserved for fire, being kept for the day of judgment and destruction of the ungodly.”
2 Peter 3:3-7 NIV
Sounds like this works quite well with a regional flood. I don’t understand how this clearly indicates a young earth. Perhaps @PDPrice can elaborate.
