What are UFOs? It is a surprisingly emotional subject. A large percentage of people who come across this article will read very little of it, having already assumed their preferred conclusion, and not take seriously the argument I am presenting. I hope that does not include you, dear reader. I wrote this to try to have a discussion about the issues rather than the current non-discussion of entrenched ideologies and people talking past each other. UFOs are real phenomena that we should be exploring, but we aren’t. I am exploring why that might be.
