It was not in their estimates of the age of the Earth - Descartes retained the biblical date.The rise of science produced a major change in attitude.In the pre-scientific world view the issue of the age of the Earth was a theological question.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.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.
