If space is teeming with life - I wonder how many different times a society advanced technology to the degree that they developed a ‘machine race’ or ‘AI’ and eventually the organic life forms died off, but the machine race would continue to grow itself out. There could be an entire solar system completely machined out. Or we could be one of the first ones doing it. Then other aliens would have to go up against our machine race because eventually they would interact. But then again, supposedly the galaxy is still moving outwardly away from itself (from the force of the Big Bang as they say) and not only that, but at increasing speeds. And not only that, but the space in between objects in the universe is also growing at accelerating rates. So the distance that is created as a result might be a built in defense mechanism to keep life forms from ever really interacting, basically then the design would enable each individual life form to have the perspective of having their own universe to themself, and they can do as they see fit. And then you wonder if this is all just a laboratory experiment on an alien planet in a different dimension, and they’re artificial planting life into the digitalized, universe-like worlds they design and they’re just studying how different life forms attempt to adapt for their science fair project. Hmmm veryyyy interesting stuff! 🙃
