As indicated earlier, the Bible does not fix the age of the earth, contrary to the claims of Answers in Genesis.

Historically, their claim comes from the work of James Ussher, Bishop in the Church of Ireland, from 1625 to 1656.

The age of the earth has been a topic of debate among Christians over the last two centuries.

Several Christian ministries promote the idea that the earth is less than 10,000 years old, which they say comes from the Bible.

Archbishop Ussher took the genealogies of Genesis, assuming they were complete, and calculated all the years to arrive at a date for the creation of the earth on Sunday, October 23, 4004 B. Of course, even assuming the method was valid, such an exact date is not possible from the genealogies of the Bible (Ussher assumed all the years the patriarchs lived were exactly 365.25 days long and that they all died the day before their next birthday).

There are a number of other assumptions implicit in the calculation.

This page examines some of the history of the controversy—what the Bible actually says and does not say—and the scientific evidence surrounding the age of the earth.

This procedure depends on temporal placement of fragments of wood using carbon-14 (C age and that also extends to a younger age.

A tree ring pattern that matches is found close to where the carbon ‘dates’ are the same. It assumes that it is approximately correct to linearly extrapolate the carbon ‘clock’ backwards. The closer one gets back to the Flood the more inaccurate the linear extrapolation of the carbon ‘clock’ would become, perhaps radically so.

Tak długo jak organizm żyje, wymienia materię z otoczeniem, tak długo proporcje węgla radioaktywnego do stabilnego w materii żywej są podobne jak w atmosferze.

Sytuacja zmienia się jednak, gdy tylko organizm umrze – wymiana przestaje zachodzić, a izotop ) atomów węgla (stężenie 1 ppt).

Udział radiowęgla w ogóle węgla występującego w atmosferze można wyrazić wzorem: w atmosferze podlega częstym wahaniom, zwłaszcza w związku z procesami zlodowacenia.
