In the prime MCU universe, the one in the same universe as the movies, what level of knowledge does the general population of Earth have about the snap/Blip.
For example, do they know that it was caused by an alien warlord using mystical artifacts from the dawn of time, and that the Avengers travelled to the past through the quantum realm to reverse it. Or were they told an inaccurate version of events to prevent panic?
Can their level of knowledge be demonstrated in universe, for example using dialog from the various MCU properties, or out of universe using statements/interviews from the writers, cast, promotional material, etc?
