Not my main hobbyhorse, but perhaps the central problem of Young Earth Creationism (even deeper than the myriad scientific problems) is that is a claim about the character of God. The deity of YEC is fundamentally a trickster god who created a universe we cannot understand. Radioactive decay is lying to us; the light from stars travel pretended journeys from the depths of time; the geology of our own planet has no consistent logic—nothing can be trusted to be intelligible, and even our own epistemological tools are incapable of understanding our world. This might be what Loki or Descartes’ demiurge would have done, but not the God of the Bible who took on human flesh to inhabit and know his own creation. Anyways, just wanted to point that out.
