When we look at our hands, are we seeing our hands, or are we just seeing the light being reflected off of our hands? And if it's just the light, what do our hands REALLY look like? My guess is we're just seeing the light, and our hands are just energy. Invisible energy. I bet everything's really invisible. We just see what we see because we have eyes that gather light and focus it on a retina that sends signals to our brains to be interpreted in our minds. So what we're seeing, in reality, doesn't really look anything like that, because everything we see is really invisible. My guess.
