With all due respect, you're putting words in my mouth. I said nothing of the kind, nor do I think that. My only question was what you feel the problem with dating methods are.

That's an argument from incredulity.
Not all dating techique can be used to measure things billions. Are you okay with techniques that measure shorter lengths of time, say, in the tens of thousands?
How? In what way? And if you do rethink and come to the conclusion that you're getting accurate results, what then?
