Mr. Niednagel - Is there any proof that the earth is not more than about 6,000 years old?
This is indeed a common question which receives a variety of responses. What "proof" is the best for a young earth, specifically one that indicates it to be around 6,000 years old? I will share with you a fascinating new discovery, and I'll try to make it as understandable as possible.
The first and most popular radioisotope dating technique which forms the basis for all of the others utilizes uranium-238 (U), which eventually decays into lead-206 (Pb). As uranium decays into lead, there are many intermediate "products" that form, one of which is helium. In other words, uranium doesn't just turn into lead without turning into a few other things first.
In any case, helium is a very mobile gas, and escapes from rocks quite rapidly. Now, zircons (crystals) have been taken out of deep granite in the Precambrian layer, which is considered the oldest layer in the geologic column. Based on the uranium to lead ratio in these zircons, they should be around 1.5 billion years old. All seems fine and dandy until a simple fact is revealed. The zircons still have large amounts of helium inside. If they really are 1.5 billion years old, then all helium should have escaped by now.
Evolutionists argue, of course, that there could be others factors involved that are keeping the helium from leaving the rocks.
To test these claims, experiments were conducted by ICR and CRS (Institute for Creation Research and the Creation Research Society) on these zircons, exposing them to a wide range of temperatures. Regardless of what they did, the results were the same. The helium continued to leave the rocks rapidly. Furthermore, based on the helium retention in the zircons, they dated the zircons to be 5,680 years old + or - 2,000 years. Remember, these are Precambrian rocks, which are supposed to be the very oldest. ICR and CRS plan on publishing their findings in a large book to be released in 2005. Be sure to look out for it. If their findings be true, it definitely gives an age of around 6,000-7,000 years for our earth.
Although I could have brought up many other indications for a young earth, I believe this is one of the best and most pertinent ones.
