Answer 2

The chicken or the egg causality dilemma is commonly stated as "which came first: the chicken or the egg?". The dilemma stems from the observation that all chickens hatch from eggs and all chicken eggs are laid by chickens. "Chicken-and-egg" is a metaphoric adjective describing situations where it is not clear which of two events should be considered the cause and which should be considered the effect, or to express a scenario of infinite regress. Plutarch posed the question as a philosophical matter in his essay "The Symposiacs", written in the 1st century CE.
