... The main difference between believing God about the Flood, and denying the Flood, so far as I can tell, is all about fossils which settled at different depths in the "library" (supra) of (sedimentary) rock. There's no denying that this occurred. What Flood deniers really really need to be true is that the different layers /strata formed over what they call "millions" and even "billions" of years. ...
The whole Flood denial is based squarely on the meaning of the measurements used to support the notion that rocks are millions and billions of years old. Without this, Flood denial collapses.
