Believers are saying that Neil Degrasse Tyson "has completely changed his tone on UFOs" but I'm not seeing it...
Users over on r/UFOs are saying that NDT has changed his mind about UFOs. I've seen nothing indicating that. For years now NDT has basically said "forget videos why don't you grab something next time you're abducted even alien trash would be remarkable." NDT has also said for years and recently that sensor anomalies could be due to sensors not being calibrated correctly and could account for odd instrument readings. Over the last few days NDT has been on the news and on podcasts going over the new government UFO videos and documents which I will say are disappointing and some videos have already been debunked. I've watched several videos of NDT on the news and in podcasts recently saying "fork out the alien" and then we don't need blurry videos or to hear about some witness's credentials because we have the alien body as proof. To my knowledge at no point has NDT said he believes the U.S. government is in possession of crafts or aliens.
