People who are indulging your fantasies are not your friends. Your friends will kindly guide you to the truth, which is that molecules are not visible with the naked eye, or even visible with a light microscope for that matter. An electron microscope won't even resolve molecule sized details. I see the same phenomenon as you do, and rather than assuming you see reality in amazing detail, it's much more likely to be an artifact of our poorly constructed eyes.
Though I don't always agree with you...I respect you for always being considerate and thoughtful...for the most part (there have been a few exceptions). You display a fair amount of intelligence and every now and then I have seen you change your mind...which is truly admirable.
Regarding human limits on perception, you are flat out wrong. We don't know ultimately what they are. Are humans going to stay humans forever? Has anything? NO!
To go into a bit of speculation, which is better then assumption...let us suppose that under the right circumstances heat itself can cause a magnification of energy particles as waves bend visible light ever so slightly...like a magnifying glass. Now...let us suppose that most people aren't paying attention, and even amongst those who do, most simply do not have well trained eyes. Not everyone sees the same...note we all don't have 20/20 vision. Cellular differences may allow for some people to see these amplified particles under the right circumstances where others simply can't see at all. I have thought about this myself after seeing what Golden Eyes describes many times before.
Golden eyes, do you see this more often when it is warm?
