You look at the sky and you wonder how could it be that we are alone? How could it be that you live on one star in a sea of stars and it just so happens that you are the lone intelligence living on only one of the countless stars? It is like an intelligent bacteria living on a grain of sand on a beach looking out at all the other countless grains of sand and thinking, “There could not possibly be intelligent bacteria life out there on any other grain on sand. I’m alone.”
“What seems to be the more logical conclusion”, you wonder? The observation is that we are but one grain of sand on the beach and yet we have never heard anything from any of the other grains of sand. Should we conclude we are alone or that an advanced species is already with us but we do not know it? Communication has already been established, we are just not aware of it. Perhaps they are not aware of it themselves because; some of us are them. Which would be the more likely conclusion in a universe that is much older than we are - nothing to be seen or something that cannot be seen?
What could be their purpose and what philosophy of life could have enabled their species to have evolved so far beyond us and have prevailed for so long? Why didn’t war between groups kill them all off as their technology became potentially deadly as it would in any advanced society? Are they one of the space-faring species that have survived beyond the groupism stage of development? How could they do that? Are there any grains of sand that have survived? Will we?
