I think all you pointed out is evidence our UFO stuff is bunk.
The time frame and technology needed to travel here would be so beyond anything we can imagine it is absurd that they’d be like they supposedly are here.
And in the 1700s if you spoke of traveling to the moon you would have been burned at the stake as a Witch.
You only need look at what technology has done in the last 125 years to imagine what a civilization 100s of 1000s of yrs older might accomplish.
Just because it seems impossible doesn’t mean it is.
