One of the challenges all methods have is that they assume a generally “static” earth/cosmos.
i.e. we know that so much decays every year, but that is assuming an environment like the one we live in today.
OK, let's toss out radiometric dating. Examine the progression of sedimentary deposits out west. The deep sedimentary basins of Pennsylvania and Texas. Those took tens of millions of years to form and show constant shifts in depositional environments that cannot be explained by a single flood. You also have at least three orogenic cycles evident in the Rockies. Even in the shorter term, there have been multiple glacial cycles during the Pleistocene, and those run in cycles of tens of thousands of years. There is no way that can rationally be explained by a young Earth model.
Just because some features can be explained as quick-forming by catastrophic events, such as the Channeled Scablands in the Pacific Northwest, it does not mean that all things in geology can be shoehorned into such.
