Your earliest geologists were operating from a false premise, young Earth.
Every time I ask for confirming evidence against the Flood, either nothing is provided, or I have readily discredited what is provided by exposing its failings. I await your premiere airtight example, or have you given it up already?
But they refuted their own false premise, showing the self correcting nature of science.
Today we have a world full of global sediments and not a trace of a universal deluge anywhere to be found. Unless there is some evidence of 20 mile high giants having roamed the earth we need not consider their existence. Likewise for a global flood. Apparently neither 20 mile tall giants nor global floods ever existed OR they left no evidence of their existence.
To date you have failed to provide any evidence of a global flood, ergo....
