How old is the Earth and the universe? One can count backwards through the biblical begats to get a figure, but late-18th-century geology began to reveal a vastly older Earth. This lecture looks at attempts to date the Earth, the hints that it is vastly older than the Bible implies, and the responses from religious figures to this redating. Similarly, cosmogonic (origin of the universe) speculation has involved both scientific and theological minds equally over time. Significantly, the historical “battle lines” between rival interpretations of both the Earth’s and the universe’s ages and origins do not map out on simple religion/science lines but, instead, reveal a more complex picture rooted largely in social and professional differences.
