(Hannah’s first question) I would rather point you to good online material, which are written by people who have a background in science, than give you an answer myself.Scientists who are Christians tell us that Carbon Dating is a friend of Christians.Neither of these assumptions is provable or reasonable.An illustration may help: Imagine you found a candle burning in a room, and you wanted to determine how long it was burning before you found it.You could measure the present height of the candle (say, seven inches) and the rate of burn (say, an inch per hour). I had the same thought about the circular reasoning involved in estimating the age of the earth, and even told my teacher that it sounded absurd.
Although this technique looks good at first, carbon-14 dating rests on two simple assumptions.
They are, obviously, assuming the amount of carbon-14 in the atmosphere has always been constant, and its rate of decay has always been constant.
The problem lies in the assumptions made by scientists when using Carbon Dating. It is just that they assume that the environment on the earth has been fairly constant, whereas Christians have sufficient reason to believe that the earth’s atmosphere has changed in the last 6,000 years.
Do read the following articles about Carbon Dating.
My doubt now is this: The age of fossils is estimated based on Carbon Dating—measuring how much Carbon-14 is present, and using the halflife principle. She, being a faithful Christian, told me to write what the textbooks stated for the sake of the exam without arguing.
