I really hope it just broke apart... because the alternative is that somebody has an anti-satellite weapon that is fairly discreet (not as obvious as a missile fired from the ground) and that they're willing to actively use.
Yeah, there's lots of stuff in orbit, and these are just the objects large enough to be tracked by radar. An impact from a small, fast-moving object is a completely rational explanation.
I remember watching a Tech Ingredients video where I think they did the math on space lasers, I think the conclusion was that it would be technically possible to significantly impact local earth surface temperature with one. (Might've been a degree or two extra for 10km² or something like that, with a huge satellite, maybe around the size of Hubble, or bigger.)
Of course, there's no reason to believe some politicians' insane ramblings about "Jewish Space Lasers".
If the topic seems insane, the caveat at 31:50 should probably correct the tone. This man doesn't actually believe space lasers were used to start a big grass fire.
