I appreciate your civil post.
Some of the basis for assessing the deep age of the ice-core drilling, is based on circular reasoning. (Such as, back in '94, scientists dated the ice core of the Greenland GISP2 through their discernment of what they thought were
yearly patterns of much
volcanism, dust, ions and isotopes found in the ice, among other details. [Since when are volcanoes, annual?] They determined an age of the 9,000-foot-depth core at about 85,000 years....based on other scientists calculations who had built a “SPECMAP”, a timescale relying on the understanding of a steady accumulation of seafloor sediment, ignoring the
volcanism that is abundant in that area! Certainly, the catastrophe of the Flood would have caused an increase in Earth's geology! The Bible indicates that 'mountains rose --
Psalm 104:8.' due to the water.... that was a lot of weight on Earth's crust!)
Circular reasoning can be like finding a fossil next to a fossilized coelecanth, and then assuming it's "at least 65 MYO"! (Scientists thought it went extinct 65 mya, but it still lives.)
Let me ask you this: mountain ranges, like the Himalayas, are determined by leading scientists to be
tens of millions of years old. But if you look at them, the mountains' features (
not the rocks themselves, but the features they form) are fresh, sharp, and well-defined....
nothing like you'd expect from objects that experience a lot of bad weather, i.e., erosion-causing elements! If they were truly that old, they'd be rounded stumps!
I believe the Earth
itself could be billions of years old, but not it's topography. I'm not a YEC.
