Planet earth - part of the milky way. In a small solar system. Without Jupiter, we wouldn't be in the orbit we're in, and animal life wouldn't exist. Poised between venus and mars, we're at just the right distance from the sun to not fry or deep freeze. And even still, a few thousand miles difference makes all the difference between incredibly hot summers and incredibly cold winters, all based on our tilt.
The planet spins, the sun spins, our planet goes in circles around it a unimaginable speed.
So in this galaxy, we're on the far tip of one of the spiral arms, swinging around the universe at an even more unimaginable speed-
In the galaxy, we aren't in the city or burbs either- being on the tip of the spiral arm, we're about as far from rest of the galaxy as is possible, living in the most rural of rural locations...
Which is why we see so few stars vs. what you see on the milky way pictures- We're stranded, in the middle of nowhere, all alone. Aliens probably don't visit us simply because we are too far away from the party. They probably don't even know we exist. Think about it- if you lived in the center of the galaxy, and millions of solar systems were within a visible range, why would you even send a probe out to the far end? perhaps they sent one, but to a different arm of the spiral?
In the end, there's no other habitable planets anywhere near us that would be explorable, much less able to be colonized before we inevitably destroy ourselves.
It's a zero-sum existence. Mankind will likely be gone for hundreds of millions of years before any intelligent life discovered our existence, and at that point, they would study "artifacts" in the same manner we study the dinosaurs.. with fascination, as well as to discover we were too stupid as a race to survive our own intelligence.
How's that for some upbeat philosophy?
