Electromagnetic or electrostatic forces are a much more likely explanation for the behavior of the sun and moon's circling the earth. It even works in favor of a spherical earth as it gives a more practical means of how objects remain affixed to the spheroid globe.
That one professor Robitaille who ripped Mr. Dave to shreds, while not a geocentrist or flat earther, has some very solid evidence for the sun being electrical in nature and not the huge fusion engine claimed by modern science. Mr. Dave ripped him for his theories, and he proceeded to take him apart and expose the fact that Dave has no idea what's he's blustering about.
As for Mr. Dave humiliating David Weiss, he deliberately created that perception because, rather than actually arguing point by point, he would spout off a concatenation of 50 ideas which remained unproven and which he took for granted, and repeatedly engaged in mockery and derision while doing it, and then if Weiss couldn't respond to every one of them, he was seen to have "lost" the point. It was smoke and mirrors. I wrote about this same tactic before when the representatives from the Kolbe institute debated those atheists. They employed the same tactic, just rattled off at high speed a concatenation of unproven and contested points and then claimed victory. Each of the points would have required 30 minutes to do justice to and to make an adequate refutations, but by simply piling them all on, they gave the impression of winning the point simply by stating them. It's a very dishonest sophistic debating tactic.
If I had the time, I'd do the analysis by pointing it out piece by piece and exposing the tactic, but it's very obvious what he's doing. I likened it on that other thread to the modern forum of "debate" in schools that caused me to walk away from college debate in disgust.
