It seems more than likely that most alien species would have eyes (or at least some sort of visual receptors), given their immense value. Yes, I know that other species could live on planets in total darkness, but I highly doubt that given that handicap, they would advance to the point of even a Kardashev Type 1 civilization. Maybe giant bats at best. Not discounting nature's ingenuity, only saying the most likely reality given all we know about life.
telepathy man. they don't need light receptors. they can read minds and see into the future.
Good point. I was thinking that too. Or was I thinking it? Maybe the aliens were thinking it for me...
