== Several facts missing in this article ==
There are several facts missing in the article, in its place are a lot of religious ideas that have no place in a scientific article. Please fix a.s.a.p. and provide the truth.

Following the [[scientific revolution]] and the development of radiometric age dating, measurements of lead in uranium-rich [[mineral]]s showed that some were in excess of a billion years old.<ref name="Boltwood">{{cite journal

The statement that "Charles Lyell supported Hutton's idea in 1830, in Principles of Geology" seems inadequate. Did Lyell set forth a scientific theory about an Old Earth in 1830? I'm skeptical.--[[User:Aschlafly|Aschlafly]] 12:38, 18 June 2007 (EDT)

:Lyell was a geologist who created several theories related to the geologic age of the earth, including I believe uniformitarianism, and contained in his book ''Principles of Geology''. [[User:Karajou|Karajou]] 12:50, 18 June 2007 (EDT)
