Yea I saw ole' AronRa's utube video, the scenes from Conan the barbarian was a nice touch. Generally Bible scholars who take the time line of Genesis seriously can vary that actual time anywhere from 6,000 to 8,500 years. Add to that the problems with radiometric dating and you have world civilization beginning between 8,000 and 10,000 years ago. The Geneaologies of are more of a bloodline, what wikipedia calls
Ethnography.
Time lines vary and one of the things that finally turned me against this whole concept of an Old Earth was this;
What can one observe about these results? First and foremost is simply that they are wrong. A correct answer would have been "zero argon" indicating that the sample was too young to date by this method. Instead, the results ranged from 0.35-2.8 million years! Why is this? A good possibility is that solidification of magma does not reset the radioisotope clock to zero. Probably some argon-40 is incorporated from the start into newly formed minerals giving the "appearance" of great age. It should also be noted that there is poor correspondence between the different samples, each taken from the same rock.
"Is the Lava Dome at Mount St. Helens Really a Million Years Old?
Most Creationists are into this whereas I am not, they come up with some interesting things. If you are interested in what they actually think instead of childishly mocking them you might learn something here:
There are circumstances that provide opportunities for testing. Dinosaurs which are supposed have lived at least 60 million years ago, should not yield dates of thousands of years. Rocks known to have formed in historical times should not yield dates of millions of years
Radiometric Dating
The radiometric dating is unreliable and the Adamic Genealogy does not provide an exact time line. What is informative is that civilization begins thousands of years ago, not millions as Darwinians would expect from the mythical stone age ape men to early organized societies. Most of them started right around 10,000 years ago which is pretty close to what the Creationist would expect and the Darwinian has no explanation for.
Have a nice day
