In the final pages of today’s Generations Forged #1 from DC, the audience — and the 1939 Batman — learn that there’s a “linearverse,” the timeline overseen by the Linear Men, in which the heroes and villains of the DC Universe age slowly, allowing for everything in the company’s long publishing history to have all happened on one Earth. This may (or may not) be the main DC timeline, but one thing is for sure: along the way, there’s a heavy implication that none of the various reality-destroying events of the last 35 year or so have actually destroyed reality at all.
