You know that dating methods are based on evolutionary assumptions, so stop trying to bluff your way through it.
No they aren't. Absolute dating techniques are based on physics (e.g. radioactive decay) and processes of physical geology (e.g. the cooling of magmas). Not a single thing to do with evolution, or anything related to biology.
The modern scheme of relative dating (i.e. the geological column with it's major divisions) was worked out by geologists who were creationists to a man, and was in place decades before Darwin published. How can something that was done entirely be creationists be based on "evolutionary assumptions"?
