Because it is, so far, just hearsay with no physical evidence. It's a curious moment: the US military has recently been more transparent about UAP, including releasing videos. NASA has a permanent body investigating UAP reports. And some seemingly serious people make seemingly serious claims about stuff other people have said exists. It seems to me that official bodies are treating these reports with more public seriousness than they have in the past. But, thus far, none of the reports or "evidence" is at all compelling. And, in a general social climate of distrust of political authority, distrust of scientific processes, and general conspiratorial thinking, these claims must be treated with skepticism. I look forward to seeing comprehensive, repeatable, multi-national analysis of previously unknown materials. Until then ... pfffft.
