I seriously doubt we have been visited by them ...me too. If nothing else than the general vastness of space prevents a simple hop-skip-and a jump over to the nearest planet / star.
nor do I believe we will ever have interactions with them ...me too. IF they're smart enough to overcome the hurdles of distance and time, then I'd imagine they'd not be interested in anything we might have to contribute. For instance, I'd imagine that you've not tried talking to the ants in your driveway anytime recently. I know that I haven't. :-)
Nice to be on the same wavelength as someone. lol!
In recent years I’ve arrived at the decision that we’re better off not finding “intelligent” life.
For a race wishing to move beyond their home planet, intelligent life is a horrible find. A planet with intelligent life would be a planet off limits to settlement.
What we need is life we can eat, air we can breathe, and water we can drink.
