However, rocks and other objects in nature do not give off such obvious clues about how long they have been around.(Perhaps it was because of isolation and the pressure to cope with a worsening climate as the continent dried out after the Ice Age.) They, like other peoples, are made ‘in the image of God’ (Genesis ).Then, in 1999, Thorne (not to be outdone) and other scientists from the Australian National University published a new comprehensive study on the age of Mungo Man. Bowler and Magee described this 20,000-year stretch as ‘commendable in intent.’ There was just one small problem.We will deal with carbon dating first and then with the other dating methods.
Carbon has unique properties that are essential for life on Earth.
The thing that makes this decay process so valuable for determining the age of an object is that each radioactive isotope decays at its own fixed rate, which is expressed in terms of its half-life.
