`  Whatever, the original disambig. line was more accurate - ``''This article describes the historical development of the estimation of the age of the Earth, concentrating on scientific dating methods...`` - that's what the article does - including a short sentence on pre science methods. But the change ``this article details scientific methods..`` is not as accurate. User:Stevertigo's edit 'this article focusses on scientific methods`` is better than the current state.   I don't know exactly why it was changed since it 'wasn't broke' before - now it's not as good for apparently the sake of being one line shorter. That's no good. I'd like to just change it back. `
