Gimme a break. The "problems" you mention in "other comments" come from someone talking about a fiction: War of the Worlds.
But if you're going to discuss the hypotheticals, like why they might visit or reveal themselves or not, I think it's interesting.
Why assume they would just show themselves openly?
Sure, people use the lack of "public open mass contact" to dispute that ETs exist. But that's only 1 theory that fits that data point (but doesn't fit the centuries of accounts, and now video evidence of sky vehicles).
I think it's interesting to consider many other reasons why we have not had "mass open contact":
- humans are idiots and we're not worth the effort. Has a representative of any country ever gone to an ant hill and done an official representation species-to-species? But actually ants are pretty clever, so it does not do them justice.
- maybe they're private and sensitive, and scared of our germs.
- maybe they're just not very sociable. They prefer to stick with their own kind.
- maybe they don't care that it would be a "big thing" for Earth/humanity. To them, using portals to travel the universe is not a big thing.
- maybe they are doing "secret surveillance" to observe the Earth lifeforms and they don't want to distort the data by interacting
- It would mess us up to much. Prime directive.
- Our world government thinks it would mess us up/ mess up the status quo too much, and they negotiated a "stay" on open contact.
- The ETs have no interest in suppressing nor promoting us, they just use Earth/Moon/Solar system as some sort of transit point, and openly revealing themselves would complicate their goals.
- There has been mass contact, in small stages, but it's been so muddied by disinfo and shaming that people think there hasn't been.
You can spend all day thinking about reasons for and against. It's fun, but it doesn't address the video evidence and "contact" accounts. Why not a #"Me Too" moment for UFO contactees? Doesn't everyone have a right to be heard and believed before being subjected to further scrutiny and investigation in order to establish believability?
