This is (or something like it) is the most likely scenario based on what we know. I'm amazed at the number of people who fail to apply Occam's Razor in this case, especially when UFO sightings have been used as disinformation in the past.
And honestly given the way things tend to happen in this universe I don't know if it's all that valid.
It's just weird to see people pull it out during a debate as a legitimate argument.
