The account in Genesis is replete with miracles that do not stand up under rational analysis.
During the early part of this period there was a considerable amount of activity by runs from AD 1850 to the present.He would have answered that the Earth was ancient, that there had not been a Noachian flood, and that the species of life had not been fixed over the history of Earth.In short, Genesis was an allegory and not literal history.It was not ruled out, per se, but it was not necessary. In the new science, however, rational explanation was desirable. In 1640 Ussher produced his famous calculation that the Earth was created in 4004 BC.In 1637 Descartes produced a cosmogony that was highly influential for more than a century. It was not in their estimates of the age of the Earth - Descartes retained the biblical date.Many authors choose to present the history of a complex subject by breaking it up into major threads and following the history of each thread separately.
I have chosen instead to provide a chronology of significant works and their authors with a view to providing a sense of how perspectives on Geology changed over time.In this period a number of comprehensive cosmogonies were proposed.These were long on armchair speculation and short on substantive supporting evidence.The story of this great change in the conception of the history of Earth is not a simple one.The chronicle of this great change can be broken into five periods; ran from AD 1600-1700.Ussher accepted the Biblical account at face value, relying on the Biblical genealogies and on extant historical records.
