Ice cores can get us back about 70,000 years in Greenland and 400,000 in Antarctica. Dendrochronology can get us back a lot further than 5k years. The oldest living tree may be about 5000 years old but long dead preserved trees also provide ring data. Making a young earth an article of faith is foolish. A lot more emphasis is placed on the plan of salvation and that is really the important part isn’t it?
