Ok. Not really sure what you’re getting at here tbh. But I assume you have read some paper that said that this tree had some isotope of some material, and you’ve taken that to mean the earth is older than 6,000 years?
No, you have data that you’ve interpreted to mean that the trees are older than 6,000 years old. What is that data, and why have you interpreted it in that way?
It's not faith when a bunch of different people all did the homework and came up with the same answers. Especially when they're all part of a system that rewards new discoveries, and they did the homework in very different ways.
There are mountains (both literal and metaphorical) of evidence for an old earth. The only evidence for a young earth is a book which contradicts its own creation story in the first two chapters.
