Things don’t just evolve around everything. Extinctions are common.
My question is, if the earth was substantially already formed when the supernova went, where is the remnant of that supernova today? They don’t go up in a puff of smoke.
I’d wager the supernova went off before the earth even formed
in a so-called stellar nursery, where the shock wave of the explosion initiated the collapse not only of our own solar system, but probably many others. The black hole, if one formed, is still around, but has orbited the galaxy 20 times by now and could be anywhere and have merged with others. Its nebula would have disappated long ago. In other words, evidence would be very hard to identify now; we’re talking about events that happened 4.5 billion years ago.
