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.
All'inizio del XIX secolo,  se eravate geologi e discutevate  dell'età della Terra, dovevate spiegare la coerenza o la mancata coerenza con l'età della Terra implicata dal racconto della Genesi.
