Origins Part 5: Older than Dirt

How old is the earth?

I hope you have read the other posts before this, because I don't feel like repeating explanations of the laws of time and thermodynamics.

How do you tell how old something is? Usually, you look for trends associated with aging and try to figure it out that way. Carbon-dating is a popular but inaccurate method, as it assumes that the samples are not affected by their surroundings in terms of carbon.

Carbon tests of historically chronicled hardened lava yielded the result of several million years. A chicken bone from a two-year dead chicken also yielded a huge amount of time. Apparently, Carbon dating is unacceptably inaccurate.

However, there are other tests that can tell us an estimate of how old the earth is. The earth's magnetic field drops drastically every year. By putting the equation in backwards, we can see that 10,000 years ago, the earth would have had a field greater than that of the sun. Since this scenario seems unlikely, we can assume that the earth is under 10,000 years old.

The moon is gradually getting closer to the earth. Again, working backwards, it would have been outside of the planet's gravitational pull 10,000 years ago.

From this data, we can conclude that the world is indeed under 10,000 years old.

"But, what about all the millions of years I learned about in school?" is probably what you're saying now. I hate to be the bearer of bad news, but those millions of years were a bunch of fairy tales that you should never have been taught in a serious learning environment. Why would someone lie to you about this on so large a scale? I will try to address that in a later post. In the meantime, you should post a comment below.

  1. There are other forms of dating objects by the half-lives of chemicals, but those methods are also highly inaccurate. Obviously, judging objects to be millions or billions of years old is not acceptable evidence.

  2. FOR THOSE KINDS OF METHODS GO TO PRINCETON UNIVERSITY.
