In a religious perspective, God created chickens; and hence the reason the chicken came first. But for a more scientific, or biological, perspective the chicken came first from evolution.
The chicken evolved from another creature, but eggs can't evolve.
As a Christian, I believe that God created all living things with his bare hands, so therefore the chicken came before the egg. (But I'm religious, so.)
This is obvious to all people who are christians God created chickens first so they could make eggs
So, this is actually an interesting, wrongly phrased question. The question should actually be "Which came first, the chicken or the chicken egg." If the options are just the modern chicken and any old egg, the answer is obviously egg. Dinosaurs laid eggs. Fish laid eggs. Heck, you could even consider mitosis to be egg laying! But when you ask which came first out of the chicken or the chicken egg, it gets more complicated. Its a paradoxical question which needs to be further looked into. The chicken lays the egg, the egg hatches the chicken. Neither could exist without the other. So then, how did the chicken come to be? And in that case, who came first, the adult female or the newborn female? Both needed to have existed before the other. So this question is not even a scientific question. It is historical. So, farmers, where did that first chicken come from? Probably not from dinosaur times, but they have been around for a while. Not as long as humans, though, because they are dependent on humans. We are actually the reason they are flightless! But anyways, which came first? The chicken. This is because any egg can hatch anything. It has what are called stem cells in them, and these cells have the ability to be literally anything. This happens with humans too, guys! So, an egg with stem cells in it hatched an egg. What probably happened was that a fertilized bird egg was found by a caveman-style farmer, and the farmer unknowingly genetically mutated that egg. Maybe by puncturing it and a bacteria found its way inside, which combined with the preexistent cells to make what we now call the chicken. That mutated egg hatched the first ever chicken, yet it was not a chicken egg. This is simply because of the fact that chicken eggs are defined as "Eggs produced by chickens that hatch chickens." This is why the chicken came first, not the egg.
There were eggs in the time of dinosaurs, there were no chickens alive in the time of or before the dinosaurs, thus the egg came first
What ButterCatX said.
The chicken egg came before the chicken as the chicken evolved from prior creatures and emerged from the egg which was laid.
because the chicken came from the egg
Pretty much what nox said.
