The simplest explanation is not always the most fun. Yes, you could say a school of mutants has always existed in West Chester, NY, but chose not to engage in any of the world threatening struggles– boring, (and also, very unlike the X-Men to ignore such threats). And the Baxter Building has been in the Microverse the whole time? –not buying it.

You could solve it easily with time travel, via the Infinity Gauntlet, with Captain Marvel resetting the entire universe, but one of things is not like the others– enter the XMen in an end credit trailer to the deafening screams of Marvel fans (I would be one of them), as Stan Lee begins reading a copy of the Daily Bugle with Fantastic Four on the front page. This is certainly scifi plausible and would be acceptable, but I have another theory..
..during the final battle with Thanos, Scarlet Witch alters reality with her magic, destroying the Infinity Stones, ceasing Thanos to have ever existed, but also inadvertently alters the reality of the universe. The previously vaporized superheroes return and BOOM the XMen now exist, and have always existed according to everyone, except Wanda. Wolverine, Rogue and SpiderWoman (Jessica Drew) are standing beside their teammates, the Avengers, The Fantastic Four can be seen far away atop the Baxter Building, and far, far away, the Silver Surfer makes a deal with Galactus to save Zenn-la.
UPDATE: this was, so very, very unfortunately, just a rumor. origin: Den of the Geek, but is it any worse than Bleeding Cool “Breaking the News” that the Batmobile was stolen off the set of Batman v Superman? I wanted to believe it was true, like so many others; it should be true. 20th Century made a statement today that clearly denied this rumor in no uncertain terms, “the movie rights to the Fantastic Four and all of its properties are still owned by Fox.” sad, but true. the below is the original post. until next time geek friends..
Josh Trank’s horrible reboot did serve a purpose, now Marvel can make an awesome Fantastic Four movie, which is planned for year 2020, and now Marvel can incorporate the Fantastic Four into multiple movies along the way. more importantly, the movie rights to the Silver Surfer come along with the Fantastic Four. Marvel can FINALLY make an awesome Silver Surfer movie with Zenn-la, the Watchers, Galactus and so many other awesome deep space characters. and even more importantly, the movie rights to the SUPER SKRULLS come along with the Fantastic Four!! and yes, that means SECRET INVASION will happen!! Secret Invasion is one of the greatest comic book stories ever told and now Marvel can tell that story properly; (also Jemma Simmons / Agents of S.H.I.E.L.D. may already be a Super Skrull).
this rumor that Marvel has regained the movie rights to the Fantastic Four and other Marvel characters is courtesy of Den of the Geek, which explains was a deal between 20th Century Fox and Marvel, in exchange for Marvel allowing two new X-Men/ mutant related tv shows ‘Legion’ and ‘Hellfire,’ announced yesterday.
