Which came First: The Chicken or the Egg?

The chicken or the egg -- one of life’s greatest mysteries. At least, it was one of life’s greatest mysteries; it’s not anymore. On a basic level, this question deals with issues of causality (with cause and effect). The question is used to highlight instances where it is impossible to say which of two things existed first (which is the “cause” and which is the “effect”). In essence, the question goes: Chickens are hatched from eggs, so how can you have a chicken without first having an egg? But a chicken is needed in order to lay an egg that hatches into a chicken, so how can you have an egg without having a chicken?

Does your brain hurt yet? Because mine kind of does.
