Why does the egg come before chicken?

This is a classic question that has been debated for centuries. There is no definitive answer, as it depends on how you define "come before."

If you define it in terms of evolution, then the chicken came before the egg. Chickens evolved from dinosaurs, and the first chickens laid eggs.

However, if you define it in terms of causality, then the egg came before the chicken. In order for a chicken to exist, it must hatch from an egg.

Ultimately, the answer to this question is a matter of opinion. There is no right or wrong answer.
