Fossil Dating Methods: Pick Your Date, Pick Your Method

We went to the Smithsonian's Human Origins web site to get evidence proving evolution is true. What did we find?

The Smithsonian web site gives several evidences they say are proof evolution. One of them is the dating of fossils. In a series of 30 SECOND videos and web pages we are looking at the various datign methods used to determine the age of human fossils.


In the previous video we looked at carbon dating of the Mungo Woman fossil. This human fossil was found near a dry lake, Mungo Lake, and originally carbon darted as 19,000 years old. By dating different parts of the fossil that C14 date increased to 25,000 years, and then C14 dating of the sediment raised the age to 26,500 years. In 1998 thermoluminescense was used to directly date the sediment the Mungo Woman was found in. The new date became 42,000 years. If these dating methods were reliable, they should all be giving close to the same date. But they don't. That's a sure sign there is something wrong with one of, or most likely both dating methods.

How does thermolumaniscent dating work? Quartz crystals store light energy when exposed to the sun. When quartz crystals are heated they emit light, and the amount of light is related to the amount of radiation stored in the crystal structure of the quartz. The amount of emitted light is measured and that gives the "stored" radiation level in the crystal.

Here are a couple of assumptions made when using thermoluminescent dating:

  • The initial level of radiation in the quartz is assumed to be zero (no one was there thousands of years ago to measure it)
  • The assumption is that the radiation absorption rate was constant over thousands of years.
  • It is assumed the available environmental energy level was constant

What we are seeing in the dating of the Mungo Woman fossil is that, depending on what is dated, a different age results. We also see that secular scientists accept that dating methods are not reliable. They readily switch to an older date (the greater hte age, the more prestige amd money there is for the discoverer), and discard earlier, younger dates.

good news of the cross

The gospel is not social justice nor serving others. The gospel is love in action... Jesus Christ giving Himself so that you can be saved from the wrath of God.

Now I make known to you, brethren, the gospel which I preached to you, which also you received, in which also you stand, by which also you are saved, if you hold fast the word which I preached to you, unless you believed in vain.

For I delivered to you as of first importance what I also received, that Christ died for our sins according to the Scriptures, and that He was buried, and that He was raised on the third day according to the Scriptures, and that He appeared to Cephas, then to the twelve.

After that He appeared to more than five hundred brethren at one time, most of whom remain until now, but some have fallen asleep; then He appeared to James, then to all the apostles; and last of all, as to one untimely born, He appeared to me also.
- 1 Corinthians 15:1-8
