A recently killed seal at Mc Murdo Sound gave an age of 1,300 years. This is caused by the well known "reservoir effect." These particular seals fed: "..of animals that live in a nutrient-rich upwelling zone.The water that is upwelling has been traveling along the bottom [of the ocean] for a few thousand years before surfacing.God confounded the speech of the people in that city so that they could not understand each other's language.They then left Babel and radiated in all directions, forming new civilizations around the world.For example, they tested a piece of wood from Pharaoh Zoser's tomb with the known tomb date, which was known to be circa 2700 to 2600 BCE. Since then, extended calibration checks have been made using U. bristlecone pine, German and Irish oak, and other species of trees.That work pushed the calibration back well beyond recorded history to 10,000 BP (years before the present.) Other correlations have extended that to 26,000 years BP.Again, C-14 dating results on Egyptian samples before, during and after the flood were found to be accurate when the data was compared with the actual dates as independently obtained.If there were a great deal of volcanism in the 23rd century BCE, it does not show up in the C-14 data.
Samples from Egypt before, during and after the flood whose dates are precisely known have been C-14 dated without any difficulty.
New-Earth creationism is mainly promoted by people who believe that the Bible authors were inspired by God to write text that is inerrant -- free of error.
New-earth creationists obviously cannot accept the accuracy of the C-14 dating method.
Since the accuracy of the Bible cannot be questioned, C-14 dating must contain massive errors -- by as much as a factor of five.
Similarly, other radiometric measurements which do not use carbon, have dated rocks in northern Quebec, Canada, at almost four billion years old.
