In this period a number of comprehensive cosmogonies were proposed.
The chronicle of this great change can be broken into five periods; ran from AD 1600-1700.Hutton and Lyell, who held that the history of Earth was dominated by slow relatively uniform changes in an Earth with a static over all history.During the early part of this period there was a considerable amount of activity by runs from AD 1850 to the present.There were various attempts to estimate the Earth's age, working back from sedimentation rates and other geophysical phenomena.The attempts produced estimates from about 100 million years up to several billion years. The first is that the geological history was still being reconstructed.If, in the year AD 1600, you had asked an educated European how old the planet Earth was and to recount its history he would have said that it was about 6000 years old and that its ancient history was given by the biblical account in Genesis.
If you asked the same question of an educated European in AD 1900 you would have received a quite different answer.
Ussher accepted the Biblical account at face value, relying on the Biblical genealogies and on extant historical records.
He implicitly assumed that the world was created much as it is now.
Notable observations included: ran from about 1780-1850.
By the end of the 18'th century it was clear that the Earth had a long and varied history. The major debate was between the catastrophists, e.g., Cuvier, who held that the history of Earth was dominated by major catastrophic revolutions and the uniformitarians, e.g.
These cosmogonies were part of the new emphasis of science in seeking rational explanations of the features of the world. This period was marked by a great deal of field geology rather than grand cosmogonies.
