What do they know, that we do not?

A great deal I am sure.

But consider this: Could Aliens have anything to do with some of what is going on today?

What if our government knows of advanced technology that would radically change our lives?

Robotic technology that means both wealth, and that manual labor is no longer needed?

Suddenly the government is almost admitting alien life and advanced technology far beyond what we currently have.

How would life be changed, and how would government be changed, were it so, and were it not wanting to wipe us out?

If they are here, and the evidence is almost beyond dispute now, they would be able to do that if they wished.

So I doubt they are out to do anything like that. But why would such information be withheld?

Lots of issues/lots of questions.
