I think we know all of this, but we aren't born with it. We know where to place our hands to catch the ball from previous experiences. Last year in physics, I already knew most of the topics we had covered but had never thought about them. They seem complicated but you already understand them once you really start to think.
what will really tweak your noggin is how is it that when your sleeping you can literally feel someone watching you. Like when my pops used to wake me up in the mornings he realized that yelling my name wasn't working so he would come down stairs to shake me but that wouldn't work all that well and he told me he noticed one thing though... if he stood there for 10 seconds or so I would open my eyes and be all like "what do you want" lol idk I still do that sort of thing I think it is a register to the brain of someone else's energy cause that is what all living things have in common is non-depleted energy so Idk think about that one
Yes, in reply to blah, they have done studies on babies where they perform different tricks and such. It showed that even kids had a distorted view, they could still tell between possible and physically impossible. Interesting. But by your definition, a fly, when you swat at it, knows which way you will be going. I don't think that we know it, but I think that we can infer what is realistic by just our eyes. It is true though that our brain is the fastest computer ever known.
