In the early 19th century, if you were a geologist and made a claim about the age of the Earth, you had to explain whether that was consistent or how it was or wasn't consistent with the age of the Earth implied by the account in Genesis.
Když geolog na počátku 19. století učinil tvrzení o stáří Země, musel vysvětlit, jestli to odpovídá nebo jak to odpovídá stáří Země podle Genesis.
