Considering he's the same age in the 1940s, and that is confirmed to be the same character, there must be an element of time travel involved (something the Watchers do in the comics).

My theory would be that through the release order of the films, we are following his character. So like, in Doctor Who, the episodes aren't in order of when they're set, but they are in order as you follow the Doctor through his travels in time and space. The same here, we are watching Stan Lee in the order of his life, rather than the technical order of the MCU timeline. That would explain why he is post-Civil War, but the rest of the film is pre-Civil War.

As to how he got back to Earth, well, who knows, but I'm sure he'll have a cameo in Homecoming.
