If Eliezer Yudkowsky loses his bet about UFOs not having a worldview-shattering origin, what is the reason why?

·Science and Technology·ends Jan 1, 2100

This market is intended to aggregate the most likely reasons why UFO's have word-view shattering origins (for Eliezer Yudkowsky), and reward those who thought of them first. In most worlds, I expect this market to resolve "N/A", but who doesn't like the idea of finding the best conspiracy theory. I will resolve it to the answer that closest/most specificly details why, so long as it was posted prior to the "worldview shattering event" becoming public knowledge. If my resolution appears to controversial, I am quite happy to let a group of trustworthy-ish users/admins re-resolve it. This question resolves N/A if Eliezer wins this bet: (https://www.lesswrong.com/posts/t5W87hQF5gKyTofQB/?commentId=rsKjPAPqeFwQuNibD)Kudos to @Joshua's market for bringing this bet to my attention. Feel free to ask questions in the comments - if they are insightful or they help me clean up this market, I'll pay cold, hard Ṁ.
