Marvel has made yet another continuity error in MCU timeline. The Marvel Cinematic Universe is undoubtedly one of Hollywood's greatest success stories, a shared universe in which everything is connected. This very connectedness means continuity is pretty much baked into every film and TV series, but in truth Marvel has always been a lot less concerned with continuity than some of its viewers.
Sometimes this leads to pretty evident mis-steps, such the infamous "eight years later" in Avengers: Infinity War, which established Thanos' as the first Infinity Gauntlet - so what was Odin's fake based upon?
Now Marvel has stumbled once again, with Eternals. Trailers have prominently featured dialogue from Ajak in which she describes the heroism of humanity, celebrating the fact that five years ago Thanos erased half the life in the universe - and the people of Earth reversed it with a snap of their fingers. These comments suggest Eternals takes place pretty close to Eternals is set around the same time as Spider-Man: Far From Home - about eight months later, in 2024. It doesn't quite fit, and it's quite possible viewers will ultimately conclude Eternals doesn't quite fit with the timeline in the way Marvel think it does.
Avengers: Endgame's timeline has caused real problems for Marvel's Phase 4. Take the example of Spider-Man: Far From Home is closer to Avengers: Endgame than is actually the case.
It's becoming clear Marvel cares a lot less about continuity than the hardcore Marvel fans. As far as Marvel is concerned, the only thing that really matters is that both Eternals and Spider-Man: Far From Home are post-Avengers: Endgame, dealing with the consequences of what happened in that particular blockbuster - Spider-Man dealing with the death of Tony Stark, the Eternals confronting the cosmic aftermath. The precise placement will probably be decided by viewers based on the dialogue in Eternals, and given the evidence of the trailers they're likely to be a little more distanced than Moore suggested.
