In the 18th and 19th centuries, English uniformitarian geologists, James Hutton and Charles Lyell, studied current, very slow rates of erosion and sedimentation and realized the Earth had to be way older than the biblical guestimate, 6000 years.
W XVIII i XIX wieku angielscy geolodzy-uniformitaryści, James Hutton i Charles Lyell, badali bardzo wolne tempo erozji i sedymentacji i uświadomili sobie,  że Ziemia musi być znacznie starsza niż zgadywane na podstawie Biblii 6000 lat.
