To play devil's advocate, we know the film's set in the mid-'90s, and it shows Danvers flying what looks like an F-15 in her flashbacks, which only entered service in '76. That puts a fairly specific window on her timeline, though we can infer that she was likely taken by the Kree much later, unless they're introducing some aging prevention stuff they might have done to her; if she'd been 20 in '76 to get into that first bunch of F-15s, she'd be in her mid-40s in the mid-90s. I don't think they're pushing for that, and Larson definitely doesn't look that. She may have only been with them a few years, but if they wiped her memory, that would still be "her entire life" until the old stuff starts coming back to her.
