Yes, all the dating methods they use are circularly based on the geological column. They have been found to be false by finding million year old living snail shells and carbon dating on the same samples saying thousands of years instead of millions.
And the earth isn't 6000 years old, only humanity.
If you look back at genesis God separated the light from the dark and that was the first day. The ancient people of the world didn't measure days by hours like we do today. They measured a day from sunrise to sunrise the next day.
In the first few days of genesis literal millions of years could have happened in a day. Thus causing the "millions of years" being read by radiometric dating. When they date fossils, they aren't dating the age of the creature. They are dating the age of the minerals and stone that seeped in and replaced the organic materials.
