After sweet-talking Peter Parker’s Aunt May in Captain America: Civil War, Tony Stark privately chatted with the youth and revealed that he knew he was Spider-Man, showing a YouTube video of the Web-Slinger in action. At first Peter denied this, saying that videos like that are faked, and while figuring out where Peter hid his Spidey costume, Tony offhandedly responded, “Oh, you mean like those UFOs over Phoenix?” This is referring to the Phoenix Lights events that happened in 1997, and on Reddit, it’s theorized that in the MCU, these phenomenons were actually brought about by the conflict between the Kree and Skrulls in Captain Marvel. This would be a fun bit of retroactively altering history, allowing for these two alien races to be “spotted” without the world actually learning about them. In real life, the U.S. Air Force attributed the second of the Phoenix Lights as flares falling from an aircraft during a training exercise, and while the first Lights haven’t been easily explained away, many believe that these also came from military aircraft. Depicting the Lights as actual alien vessels is definitely a lot more fun to think about.
