This age-old question was first asked by Aristotle back in the 4th century BCE. Since then, the question has been seen throughout society and has become one of today's most iconic paradoxes. So which one actually came first?
The chicken came first, and then it laid an egg
Life always originates with the first living, breathing being. Therefore, the mother and producer of the egg must have been here first.
God created animals at the beginning of the world
At the beginning of the world, God created animals, not eggs. Eggs were simply one way for those animals to reproduce, but the animals were what God created first.
This question is supposed to be an infinite sequence. There is no definitive answer as to what came first, and that is okay.
There is no true origin of the first chicken or the first egg
Some things simply came to be and are outside of the boundaries of human investigation. The problem of the chicken and the egg is one of those. Without a chicken, there could be no egg, and without an egg, there could be no chicken.
