I say “sort of” because he really doesn’t believe the Earth is more or less spherical. One of Day’s recruits to his video streaming thing has been the comedian Owen Benjamin https://en.wikipedia.org/wiki/Owen_Benjamin. Benjamin had the beginnings of a Hollywood career including co-starring with Christina Ricci in an obscure film in 2009. However, his career got derailed by his increasingly extreme views. These days Benjamin pushes extreme anti-Semitic conspiracy theories which amount to a kind of unified theory in which her thinks everybody is trying to make you believe lies about the moon landing etcetera as part of a Satanic plot. It’s the usual nexus of anti-Semitism, misogyny, homophobia and transphobia with epistemic paranoia. The central theory is that people are lying about everything to make you believe lies in general.
What’s interesting here is that Day appears to be following Benjamin down the same path. Not that Day also doesn’t push the same kind of fallen-world anti-Semitic nonsense but that he’s being more open about how out there some of his beliefs about the world are — including flat earthism.
The specific pretext is this 2012 interview with a NASA data visualisation person: https://www.nasa.gov/centers/goddard/about/people/RSimmon.html The interview explains how he helped create an image of one hemisphere of the Earth as seen from space by stitching together multiple higher resolution images of Earth. Aha! Say the flat Earthers, Manipulation! Lies! etc etc.
It’s something you see a lot from falt-earth to vaccine denial to global warming denial: a rejection of any data, images, graphs etc that relies on any kind of inference or data cleaning etc. The demand is for evidence that is an unfiltered capture of external reality — which is impossible. Heck, not only is it impossible but which we know is myth at least since the time of Plato. What you see out of your own eyes is stitched together and processed and inferred.
Day sums up his position:
“Notice that ALL of the hemisphere photography we think we’ve seen has turned out to be nonexistent. It’s becoming clear that from the evolution fairy tale to the Blue Marble fraud to the dinosaur fraud and the satellite myth, the world is very, very different than we have been told it is. What is the point? To deceive you into serving Satan rather than God.”
Interestingly he gets a lot more pushback in his comments than he normally does. I guess even Day’s followers aren’t keen to adopt a flat-earth although structurally it’s no different than the anti-vaxx and anti-evolution stuff Day peddles.
In the comments Day responds with a weak equivocation:
“VD October 24, 2019 12:20 PM Jesus… The earth is not flat. What part of “fraud is being committed concerning X” leads you to immediately conclude that this means “Therefore Y”? I don’t believe the Earth is flat. But I don’t believe the mainstream narrative concerning the nature of the Earth either, because it contains too many lies. Binary thinking is usually a serious mistake.”
The “mainstream narrative” here being that the world is more-or-less spherical.
Unfortunately Day really does need to engage in some binary thinking here. Just by visiting different places in the world we can quickly observe that whatever curvature the Earth has it’s pretty much the same everywhere. Sure big mountains are pointy and oceans are flat but in both places you can observe that whatever is going on it’s pretty much the same everywhere. That is seriously limiting to the range of possibilities for the curvature of the Earth. A flat or curved disc with an inaccessible underneath would have edges with a radically different curvature. Any shape that you could circumnavigate, if it wasn’t basically a sphere, would have some spots with extreme curvature that frankly everybody would have noticed i.e. the Earth really isn’t a cube.
A sphere isn’t just one option among many for the shape of a thing. It’s a particularly special shape. If you want a uniform (more or less) curvature and no edges, then let’s just say your options are limited. Or…maybe the devil is making me say that…
