The deeper question is not really about which came before in any random pair of "chicken and its chicken egg" or "chicken egg and its chicken".

It's about how chickens and chicken eggs emerge (first means "very very first"), and it's supposed to point to this paradox: If you need both chickens to have chicken eggs, and chicken eggs to produce a chicken, how did either came about?

E.g. did something non-chicken-yet that could lay eggs suddenly laid a chicken egg? Or did a non-chicken egg suddenly produce a chicken? and so on...
