Cognition decides world

A classic question, is egg first or chook first?

I believe many people have their own answers. Like both of egg and chook were evolving, they became egg and chook through evolution. This is a good anwser. It trys to solve this question in biological way. I want to try solve it in another way. I think egg and chook are borned simultaneously. When our ancestors found a kind of animal that our ancestors definded the animal to be chook, the kind of animal became chook. So the thing is borned by chook is called eggs. By contrary, when our ancestors found a kind of thing that our ancestors definded the thing to be egg, the kind of thing became egg. The animal who born egg is called chook.

Every thing i try to explain above is when people aware a thing, this thing becomes existing thing from inexistence. Every person's world is formed by every thing he or she awares. So Cognition decides world.

Actually, i do not think i explain this clearly...
