Do you think aliens in ufos have visited Earth? (And all things UFO)

That we know of. :scratch:

That we don't know about them, that it hasn't been communicated...

What would that say about humans. Because we sure as hell don't know how to be quiet and mind our business. Can't not say what we "know."

Once again, it would mean we're the only ones who can't follow suit. We can't operate like the others. Alien?
