In Avengers: Endgame, when
Scott Lang escapes the Quantum Realm, one of the first places he passes by is the memorial park in San Francisco called Wall of the Vanished.
There he finds several stones engraved with the names of thousands of people. The in-universe reason is quite straightforward. These were the names of
all the people who became victims of the Decimation (Thanos' snap) with some of the known names (seen on-screen) from the memorial listed here.
Is there an out-of-universe explanation about the names on the engraved stones? (For example, are these names of the people, in real life, related to the MCU or some sort of Easter Eggs to characters played by the actors of Avengers: Endgame in other movies?)
