Satan, the father of lies, will use and abuse science in an attempt to "disprove" any part of God's Word. He manages to deceive a lot of folks, but not all of them .. and certainly not the Elect.
geology and archeology and evolution are in bed together confirming one another's theories
You're dead right, brother! The Great Apostasy involves a Great Conspiracy of misleading, mendacious, "scientific" nonsense that the blind, apathetic masses will fall for. Those who have "eyes" will clearly see the deception.
The problem is, no one was there to see what actually happened before, during and after the Flood. So a lot of the anti-Flood arguments are based on imagined scenarios and assumptions that could be wildly off the mark. Plus the miraculous power of God to control the forces of nature are never considered.
Wrong ... unless you're a Jehovah's Witness and one of the "144,000". Any Christian who claims to be one of the "elect" is most probably speaking from a position of pride or ignorance or delusion. Only God knows who the "elect" are.
