You are looking in the wrong direction. The effort was not spent attempting to falsify the Bible, but to demonstrate its literal truth.
Geology was founded for the purpose of demonstrating the global flood of Noah. A century or so went into the effort until, about 1830, the effort was pretty much given up. The reason was simple. The evidence was overwhelmingly against it.
And all the evidence has come to light??? We are sure of that? The future holds no surprises along these lines?
noone’s ‘given up on it’. There is constant new eivdences comingto light and has been for quite soem time- You may dissagree with what the information suggests, and that’s fine- but to state that they ‘gave up on it essentially’ is misleading.
