I was going to go off on an extended thing about how low the probability of that is, how we’ve got all kinds of evidence pointing to a construction date for the pyramids of about 4500 years ago (including physical documents from the time dealing with supplying said construction), how a solar flare wouldn’t wipe out other evidence of a technologically sophisticated civilization, and all that kind of thing, but I’m just going to point out one thing: The pyramids would have been terrible for putting people in. There’s very little internal space, so they could only hold a handful of people for a little while, until their very sparse supplies ran out. If they wanted to build shelters, they’d take advantage of the extensive limestone caves in the region. So even if there were a civilization older than 12,000 years old, which there was not, they wouldn’t be so stupid as to build such useless structures as the pyramids as shelters against catastrophe.
