The age of the Earth has been a matter of interest to humans for millennia, and today still causes debate, particularly between young-Earth creationists who hold to a date of 6,000 years or so, and uniformitarians who hold to a date of about 4,500 million years.
Increasing ages
Early Jews and even some "heathens" believed that the total age of the Earth would be around 6,000 years.[1]
Similarly, people such as St. Barnabas and St. Irenæus held that the Earth would be 6,000 years old.[2]
In 1830, Dr. Hales published a list of 120 historical authorities from various cultures who had decided on a date of creation. These ranged from 6984 B.C. to 3616 B.C.[3]
Included in Hales' list is James Ussher, who calculated the famous date of 4004 B.C. for creation. Young-Earth creationists still consider this date to be close to the actual date.
In 1778 George-Louis Lecrerc, Count of Buffon, proposed that the Earth was about 74,832 years old.[4] James Hutton, whilst not proposing a date, dismissed the Biblical account and claimed in 1785 that there was not evidence of a beginning at all.[4] Charles Lyell supported Hutton's idea in 1830, in Principles of Geology.[4]
In 1854 Hermann von Helmholtz estimated an age of between 20 and 40 million years.[4] Around the same time Lord Kelvin put his mind to deriving an age, and came up with a range between 20 million years and 400 million years. He later refined that down to between 20 million and 40 million years.[4]
The 1911 edition of the Encyclopedia Britannica discussed dates up to 500 million years.[5]
By about 1930, J. H. Jeans was arguing for an age of the Earth of around 2,000 million years.[6]
The currently-proposed age is 4,500 million years, based in part on rocks dated by Potassium-argon (K:Ar) dating at about 4,400 millions years.[7]
