UFO timeline project

Hi everyone! The topic of UFOs or UAPs has always intrigued me. Like many of you, I've had the opportunity to read countless stories, documents, books, etc., about the phenomenon. We know there's something out there, but we have so many puzzle pieces that it's hard to determine the exact truth. So, I was thinking we could collaborate to create a probable timeline. Obviously, we’d be making assumptions, but this could help us filter all the information we have at hand. We can create different timelines and see how they fit with reality.

For example, in the image I’m sharing, I started the timeline focused on the Roswell incident, followed by the supposed interaction between President Eisenhower and extraterrestrials. Then, I included the cases of Bill Herrmann and Herbert Schirmer, as both are very interesting, and the extraterrestrial beings in both stories share a winged serpent symbol. Additionally, in Herrmann's case, the aliens mention that they attempted to contact our representatives, but the government tried to capture one of their ambassadors, etc.

What do you think?
