There are three standard creationist responses: First, creationists assert that current rates (Y) are different than past rates.It is possible that these rates changed — but under uniformitarianism, which is necessary for science to function, we must assume that rates did not change unless there is evidence for this change.Dalrymple, referring to metamorphism and melting of rocks in the crust, has commented: "If the rock is heated or melted at some later time, then some or all the In a recent study 128 Ar isotopic analyses were obtained from ten profiles across biotite grains in high-grade metamorphic rocks, and apparent Ar-Ar "ages" within individual grains ranged from 161Ma-514Ma.is known to cause grave problems in regional geochronology studies.Third, creationists ignore the evidence and deny that [X] exists altogether or assert that belief in a Young Earth is based on faith, not science. These ages weren't just made up — or, worse, accepted to "give evolution enough time".Each was concluded from a range of experiments and observations made across multiple disciplines of science, including astronomy, geology, biology, palaeontology, chemistry, geomorphology and physics.
This age is obtained from radiometric dating and is assumed by evolutionists to provide a sufficiently long time-frame for Darwinian evolution.
This article collects evidences that place a lower limit on the age of the Universe beyond the 6,000 to 10,000 years asserted by most Young Earth creationists (YECs) and the literalist Ussher chronology.
All of this evidence supports deep time: the idea, considered credible by scientists since the early 1800s, that the Earth (and the Universe) is millions These limits usually take the form: "Because we observe [X], which occurs at rate [Y], the universe must be at least [Z] years old".
This challenge is mainly headed by Creationism which teaches a young-earth (YE) theory.
A young earth is considered to be typically just 6,000 years old since this fits the creation account and some dating deductions from Genesis.
