Just to kick it off, Ive been wondering just when the age of this Earth became such an all-encompassing issue for science. When did this concern first arise in a major way, and what was the putative age believed to be at that time? And, how has that belief changed over time, to the present? Dating methods in current use must have a very basic, erroneous assumption, in order for science and truth to be so far afield from one another.
The reality seems to be that it's not about finding out when the age of the Earth was first studied and estimated, but with figuring out how to make it look like it originated with Darwin.
Darwin inspired by Hutton, actually. A much younger age and cataclysmic flood was the accepted paradigm prior.
