There is "gobs and gobs” of evidence for evolution.
There is no harmonizing the evidence to support the idea of a young earth.
Little of the elaborate world building exercise which fills the pages of YEC is in the Bible.
You reject almost the entirety of science anyways, why not go the distance and just declare science to be anathema? Instead of denying cosmology, biology, and geology, just proclaim that youth in the church should not think of such matters. Pull the kids out of science class. Thunder from the pulpit that the pursuit of knowledge of nature is akin to the sordid chasing after worldly pleasures. That way, you would not have to bother with all this accelerated radioactive decay, accelerated speed of light, accelerated chalk cliffs and speleothems, accelerated cratering, accelerated everything. You could be done with trilobites and dinosaurs and the fossil record. None of that is in the Bible anyways.
