I recently remembered what I thought about during my first hour of college chemistry,
Which came first: the chicken or the egg?
The answer is: "it depends."
The first question is: "Do you believe in evolution?"
If you do, then there were fish eggs, dinosaur eggs, etc long before any chickens.
If your question was "chicken or chicken egg?" Then I need to ask you a hypothetical question (will explain after the answers): "First clear your mind of chickens. Second: If a alligator lays an egg, is that an alligator egg? Is it still an alligator egg if a turtle hatches from it?"
If your answer is that the egg laid by the alligator is an alligator egg, then the chicken came before the chicken egg.
If your answer is that the egg laid by the alligator, out of which a turtle hatched is a turtle egg, then the chicken egg came before the chicken.
(Explanation for this question: If you believe in evolution, then the way you think that a type of bird evolved into a chicken went like this: A not-chicken lays an egg, out of which comes another not-chicken, which lays an egg, out of which comes another not-chicken...which lays an egg, out of which comes a chicken. The series is: note-quite-a-chicken, not-quite-a-chicken, then finally a chicken.)
Let's try the other answer to the first question, "Do you believe in evolution?"
If not then " And God said, Let the waters bring forth abundantly the moving creature that hath life, and fowl that may fly above the earth in the open firmament of heaven.
And God created great whales, and every living creature that moveth,
which the waters brought forth abundantly, after their kind, and every
winged fowl after his kind: and God saw that it was good.
And God blessed them, saying, Be fruitful, and multiply, and fill the waters in the seas, and let fowl multiply in the earth."
And therefore, the chicken came first.
