Depends on how long ago "they" developed telescopes capable of viewing Earth with good resolution. We know in principle how to build such instruments.
"They" may have watched the Romans build roads and sussed out their mining activities from atmospheric spectroscopy. Or much earlier, signs of agriculture.
In which case they could be here...right about...just a sec, somebody's at the door....
- lucb1e 10y agoMy post was under the assumption it wasn't an alien lifeform. If that's what the person I responded to meant, then I see his/her point better. Still, if we finally found life, I'd prefer for them to be close rather than far. Curiosity killed the cat, but I'd rather learn about the aliens (if they are indeed arriving on our doorstep soon) than know they're too far away for either of us to make it in time.
