Ussher dated the arrival of Abraham in Canaan to 2126 BCE and the Noachian flood at 2349 BCE.The latter is unlikely, because historical records in both China and Egypt continued without disruption through that date, and contain no record of a massive world-wide flood that would have wiped out their civilizations.Since then, estimates have been refined; almost all have grouped around 14 billion years.Currently, there is a near consensus among earth scientists that the age of "Earth and [the rest of] our solar system is 4.54 billion years, plus or minus 0.02 billions years." Both values are in conflict with interpretations of the biblical accounts of creation by "young earth" creationists.("Annals of the Old Testament, deduced from the first origins of the world.") He calculated that God had created the Earth in 4004 BCE. John Lightfoot, (1602 - 1675), an Anglican clergyman, rabbinical scholar, and Vice-Chancellor of the University of Cambridge had already arrived at an estimate of 4004-OCT-23 BCE, at 9 AM.(We assume that this was either Greenwich Mean Time (GMT) or Jerusalem time).
These were based on the crude models then available to scientists.Many theologians have attempted to compute the date of creation by working back from this or a similar known date, through the various time intervals mentioned in the Bible.For example: Work backwards through the Book of Judges.Unfortunately, Ussher gets most of the credit; Lightfoot's contribution is rarely cited.This would make the time interval between the creation of the world and a common estimate of the birth of Christ (4 to 7 BCE) to be close to 4000 years.
