YEC was dead by 1820. A world-wide Flood was dead by 1831.
"Many evangelical Christians today suppose that Bible believers have always been in favor of a "young-universe" and "creationism." However, as any student of the history of geology (and religion) knows, by the 1850s all competent evangelical Christian geologists agreed that the earth must be extremely old, and that geological investigations did not support that the Flood "in the days of Noah" literally "covered the whole earth." Rev. William Buckland (head of geology at Oxford), Rev. Adam Sedgwick (head of geology at Cambridge), Rev. Edward Hitchcock (who taught natural theology and geology at Amherst College, Massachusetts), John Pye Smith (head of Homerton Divinity College), Hugh Miller (self taught geologist, and editor of the Free Church of Scotland's newspaper), and Sir John William Dawson (geologist and paleontologist, a Presbyterian brought up in a fundamentalist atmosphere, who also became the only person ever to serve as president of three of the most prestigious geological organizations of Britain and America), all rejected the "Genesis Flood" as an explanation of the geologic record (or any part of that record), and argued that it must have taken a very long time to form the various geologic layers. Neither were their conclusions based on a subconscious desire to support "evolution," since none of the above evangelical Christians were evolutionists, and the earliest works of each of them were composed before Darwin's Origin of Species was published. The plain facts of geology led them to acknowledge the vast antiquity of the earth. And this was before the advent of radiometric dating."
"By the beginning of the nineteenth century, the interpretation of the geological strata had changed radically. Virtually no established geologist thought that the thick sequences of stratified sedimentary rocks so evident in quarries, cliffs, and mountains had anything to do with the flood. Neptunists attributed stratification to deposition of sediments from a shrinking primeval ocean. Others suspected that rock strata represented deposits laid down in successive interchanges of land and sea, possibly over long periods of time before the advent of human beings." Davis A. Young, The Biblical Flood: A Case History of the Church's Response to Extrabiblical Evidence, pg 98.
For those interested in the history, I strongly recommend the above book by Young and Genesis and Geology by Gillespie.
What we have today are people who have made a god out of their interpretation of the Bible and refuse to accept what God has clearly told us in His Creation: the earth is very old.
