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".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.(light brown) Next, fossil-rich sedimentary rocks were precipitated.

This means that you know which events came first, but not the exact time when they happened. Scientists use the fossils of animals to help determine relative age.

However, it is time for this battle to end; Christians should leave behind the BC/AD labels and adopt the BCE/CE dating system for all calendrical references.

Christians have offered many reasons for maintaining the BC/AD system.

The evidence against a recent creation is overwhelming.

There is perhaps no greater attack on science than Young Earth creationism (YEC).
