Apologies for the click-bait title, but all of this thinking going on in recent posts has got me thinking again on something I find truly fascinating. Mind you, I'm no scientist, so I'll be murdering what I'm trying to express, so be patient with me. What we perceive is not the "real" world. The real world is just a bunch of atoms/molecules generating forces. So if there are enough atoms close enough ( and if we saw them for what they really are, still not very close as 99% of matter is empty space ), then the forces reach our eyes and our eyes "sends information" about the forces impacting them to the brain and our brain cooks up the image of the object - a desk, let's say. The shape, the color, the perception of density - all constructed for our consciousness to allow us to interact with the desk. And how the desk feels aligns with how we perceive it - it's like it really is what we're "looking" at. But it's not, it's a cluster of atoms/molecules that send forces. Sound, just more forces. So why has evolution yielded this cognitive capability to some extent to all animals? Yes, evolving the capability to generate pictures from these atoms/molecules is key to survival - but why does life want to survive? And replicate? And ensure the survival of the species? This is far more fascinating than simply believing in a God ( for which I do ).
