There are secularist thinkers who argue, in all seriousness, that our universe may be a simulation or holographic projection. To take a few examples:
This is ironic. For that position is even further along the antirealist continuum than omphalism. Indeed, it’s fully equivalent to Last Thursdayism, which is routinely used to satirize young-earth creationism.
Whether or not they believe it, secularists treat simulated reality as an intellectually respectable hypothesis. By contrast, young-earth creationism is reviled as intellectual rubbish.
But how is young-earth creationism more counterintuitive than a cosmic simulation or hologram? Indeed, isn’t young-earth creationism less radical than these secular alternatives?
I’m not using that as an argument for creationism–just observing how a secularist will allow himself a degree of leeway he’d never grant the Christian.
