but other life is likely to be so untouchably far away that we might as well be.
The thing is, though, there’s intelligent life on this planet that isn’t only not human, it’s not even primate, not even a mammal, so there’s huge scope for intelligent life out there that we may not recognise, it may not communicate in a way that we could interpret and respond to, because the thought processes are entirely different, and the physical structure of the entity may enable it to produce a variety of different sounds of different frequencies almost simultaneously, plus they may not even use any form of written language, or if they do, the symbology may be almost impossible to interpret.
Those entities may not even have hands or similar, but still have the ability to use tools, and devise ways of creating and adapting tools to changing circumstances.
Such creatures live alongside us now, I see no reason at all for many other planets to have environments capable of sustaining life that may resemble such creatures, where mammals may never have found the ecological niches in which to evolve.
There’s at least two worlds in our solar system with vast quantities of liquid water, where conditions may well have allowed reasonably complex life forms to develop.
Makes you think.
