Space is big. Very big. Bigger than words can express big. And so far, in all of our searching, Earth is the only place we know of that has life, and we are the only species that have evolved high intelligence and technology. The Hubble Space Telescope helps give some perspective, and the upcoming James Webb Space Telescope (coming in 2021) will be able to look even further back in space and time.

While space is so big that, statistically speaking, there may be other intelligent life out there, it's very possible they could be so far away that we will never communicate with them, much less visit. It's also possible we humans are the only ones out here. While it may be an awful waste of space, there's no reason that the cosmos should bend to our desires. People are listening and looking for signals, but there is no data yet.

Either way, the only thing you know for sure is that you exist right here and right now. This moment is guaranteed, but that's it. When you share a meal with friends and family, they are the only humans in the entire universe like them, and you the only human in the universe like you. Why ruin that with politics? Take the cosmic perspective. Enjoy the meal.
