Yes, that is all true. The point I am making is that the number and quality of witnesses to UFO events are much more numerous, recent, and ongoing as compared to those ancient events. Yet, the witnesses to the UFO events are not believed. Doesn’t that seem odd to you?
Plenty of people believe that others have seen objects in the air that they can’t identify. I know of nobody that rejects this has happened. To extrapolate from that to aliens from other worlds is what gives many pause. Especially when natural causes are discovered for the majority of such events.
