Talk politics.

My personal opinion is, and always has been, that we will never be able to fully understand what is out there. We're smaller than a speck in this universe. It's naive and arrogant to think we're alone in this whole universe. So does that mean aliens are flying in ships and visiting Earth? Who knows? Maybe they're not all harmful. Maybe they're just as curious as (some) of us are in regards to other life? Or hell, maybe they're even in contact with some of our governments for some reason? There is just no way to know for sure.
