You know this reminds me of something I was thinking about a while ago.

Say hypothetically Mars was green and supported life for billions of years alongside earth and had a civilization of sentient creatures on it at the same time as humans. We would have had telescopes to see them and realize there was a sentient race of beings on its surface for hundreds of years, and they would probably too but have no ability to reach each other or contact each other. It would just be a really uncomfortable, awkward few centuries of starring at each other and wondering what the other side was thinking about us...
