Eric used to peddle straight up creationist nonsense that was a wonder to behold. Take this from his series "Creation Minute" explaining why the Colorado river would have had to flow uphill to carve the grand canyon.
But since then, he has teamed up with presuppositionalist and "virtuously circular argument" making preacher Sye Ten Brugencate. Sye runs a little website called proofthatgodexists.org (which as I just checked today it looks like he let his domain registration expire, odd).
How and why did Eric go from at least trying to address the evidence and arguments to trying to use philosophy to justify ignoring it outright? Well today I came across this transitional form where Hovind explains exactly why he gave up on arguing the evidence: "it doesn't work."
