Sporty_g saidObviously we have been literally broadcasting our presence for about 75 years...radio and TV....so 75 light years out from the earth they are getting the signals we first sent back then....with all of our wars, racism, historical events....quite the information to have and form an opinion of us from...are they laughing, shocked and disgusted, or recognizing their own past foibles in our broadcasts?....
They might not even actually have eyes. Or experience time in the same way as us.
Think of the infinite different ways that life and sentience can develop. They could be anything from microscopic von neumann-ish swarm minds that live and die in a span of a second to massive mineral neural networks that would take centuries to form a single thought. We might not even recognize them as living at all. Astronauts would be mining a moon, not realizing that the dust itself was living or those weird crystals are plant analogs.
It always comes down to the problem of communication and thus perception. How would you explain color to a blind man? How can you anticipate what alien life would look like when all you know of life is the one on Earth?
The advent of astronomy certainly did one thing though: it made us realize we aren't special. There are so many fucking stars, each one a sun, each one with its host of satellites, each one with a potential to develop some sort of self-replicating chemical that in turn might give birth to beings that are aware of themselves.
The Bible (or any other human religion) certainly didn't account for that, did it?
Then there is also the problem of the light barrier... and the fact that we humanoids have only been sentient for about a couple of hundred thousand years or so, and we only became civilized for about 10,000 years. And we've only just become a spacefaring species in the last half century.
When compared to how old the universe is, we're less than infants. More so when you consider the scale everything. Where the distances are measured by how far light can travel in a year, when to us light itself seem damn well instantaneous. You begin to realize just how tiny we are, how easy it is to get lost amidst everything. Would you notice a single grain of sand in a beach if it started to glow in rainbow colors?
