In the early uses of that Earth, it's possible that Superman and Batman don't exist, then when they do they are virtually identical to the Earth-One version, then in the 1970s, much more distinction is made and we learn more about what is and isn't in their timeline, then in the early 1980s Roy Thomas does his own thing with the history of Earth-Two. So right there you've got a few different timelines.
There are also a lot of Earth timelines that fans have theorized to exist which aren't officially recognized. For example, E. Nelson Bridwell suggested there was an in-between Earth in the 1950s which was mainly just a Superman-Batman Earth which would contain some of the 1950s WORLD'S FINEST stories and other stories from their solo comics. Fans then called this Earth-E in honour of Bridwell. Of course, there's the famous Earth-B--Earth-Boltinoff--to account for the crazy things that went on in his THE BRAVE AND THE BOLD and other titles under his purview. But fans came up with hundreds of other possible Earths to account for all the continuity inconsistencies.
I also recall that among fans, prior to Crisis, some were adamant that Superman should be the first super-hero even on Earth-One. This was arguably the case prior to 1971, before Superman's timeline changed, because Superboy was presumably living in the 1920s and 1930s and therefore arrived before the big explosion of super-heroes in the 1940s. Even when Superboy's introduction was changed, you could still argue that most of the super-heroes hanging around Earth-One had only existed after Kal-El came to Earth--and remember he was doing super-feats even as Superbaby.
After Crisis, Superman was the first super-hero of his age, but since the Justice Society was supposed to be on that Earth they had to have existed in a previous age. This is maybe what made some editor want to get rid of the Justice Society. I wonder if eventually the timeline would have been changed to get them out of Superman's continuity, the same way the Legion was. In any case, you can't really say there's only been one timeline since 1986, there have been several. And I'm not clear what's in or out of continuity anymore. It's a mess that I can't follow.
This is to say nothing of the Elseworlds and Imaginary Stories. In particular, I like the John Byrne GENERATIONS Earth, where Superman is the first super-hero. And then there's the NEW FRONTIER Earth of Darwyn Cooke. And all the different timelines in the movies and T.V. shows, where Superman must have been the first super-hero.
