That was 6000 years after Gobekli Tepe was built..... And now that that some folks have figured out where to look cities are popping up every few months... In the last few years we have found 8 sunken cities out in the oceans up to 400 feet deep... The geological evidence dates the walls cut around the Spinx at around 12,000 BC..
Q: If the flood actually occured...
Could that lil event have skewed your data?
The earth is not a cleanroom lab, so how could you tell
your data is pure?
