The sun has been doing this kind of stuff for a very long time. The trouble is ... that we haven’t had some of the more serious “hits” from the sun, as we’ve had in the past in North America and when people lived here in historical times. Back then when it happened, it was a non-event, except for the glowing lights in the sky. Now, it’s the infrastructure of society that is in danger and it’s “that collapse” which would be the problem.
It’s happened before, but we didn’t have today’s infrastructure.
A lot of things have been going on for a long time including meteor showers. The issue here is how many deaths are contemplated from the event regardless of its effect in the past. When you start talking about 1 billion + deaths from the event, you’re talking apocalyptic/tribulation stuff.
