Yeah, sure the government has secret vehicles they're not telling us about. That's part of it, all right. I don't think it's all of it.

"If aliens are visiting us, we would have proof of it by now."

I think we have mountains of proof of it by now...MOUNTAINS!...but....if the powers that be don't officially release any of that proof to the public and the media, and deny that it exists, then the public can't see that proof, can they?

Yes, it might be a psychic phenomenon, as you say, but many incidents suggest it is more than that.

Yes, the government might have arranged Roswell, and might be using the ET stuff to misdirect people from other things they're doing.

Those are possibilities. You think they're doing a coverup to distract us with ETs that don't exist? Maybe. I think they're doing a coverup to prevent us believing in ETs that DO exist...because it would massively change public consciousness and threaten the present political status quo. It would make our governments look weak and dishonest and undependable, and they don't want to be seen that way.

You must be able to see that they could have strong reasons for adopting either of those coverup policies.

In the end, though, when it comes to this subject or any other, everyone just believes or favors what they would rather believe or favor, and that's an emotional decision on their part. They interpret info on that basis. I'm not a bit reluctant to admit that I have an emotional bias in favor of a Universe with many intelligent lifeforms living on many worlds, and some that can visit us. I like that idea. If you don't, well...(shrug)...that's up to you. You'll go on believing whatever you want to...and so will I.
