Aurora Borealis!? At this time of year, at this time of day, at this part of the country, localized entirely within maybe as far south as Alabama to northern California?
Yeah, because you can't prove a negative. He doesn't need to debunk it, only to provide an alternative explanation which is more likely. Occam's razor.
Occam's razor won't get you to the correct conclusion for all possible combinations of truth values and evidence, but it is always the best process to follow. You might end up getting new evidence later that means you update your belief, even update it to believe in something which previous evidence meant Occam's razor lead you to dismiss that conclusion. But it helps you arrive at the best conclusion based on current evidence.
Because assuming that is a way bigger assumption than something like "faulty hardware", especially since this guy has stories about other things that we know are faulty hardware.
I also bought into the bit flip theory but it was confirmed that the hardware was somewhat faulty which is an infinitely more likely cause than cosmic rays. There's also the fact that there aren't any bits that could be flipped which would perfectly reproduce the glitch.
I would be angry too if I have already done lots of research trying to figure this out and the top videos and articles talking about it all say the least likely thing is what actually happened.
(Or it could be an N64 memory expansion pack being flaky because damn they were flaky. It doesn't matter that your game isn't actually using the extended memory, it's still shitting all over the RAMBUS).
At least not until that civilization ending gamma ray burst thats been traveling for millions of years lazers the fuck out of our atmosphere without warning.
