The egg was there and the chicken was also there inside. The chicken was conceived in the egg by cross-bred before the egg came out to this world.
Actually both are there but we see the outer and forget to see the inner.
The egg contains the liquid form of chick.
Hence both came first to this world.
There is no intelligence in quoting this in conversation. It only reflects the innocence of a speaker, we are prone to certain kinds of communication without knowing the depth of a quote. Why we argue whether eggs came first or chick coz it creates a myth of intelligence practiced by scholars. If you sit and walk inside of any question you know both are present but only one is visible to your eye..
I know some people say they are not interested in reading about old philosophers but when you watch their conversations which are entirely filled with these types of conditioned metaphors or quotes of old philosophers. I understood, we are deeply embedded with these in everyday language and cannot be erased because it slips out of our unconscious mind.
