CMV: The chicken came before the egg

I am of the believe that, in regards to evolutionary biology, the chicken did in fact precede the egg. I admit, my specialty is neuroscience rather than broad evolutionary biology, but I fail to see any compelling reason or science for why the egg would come before the chicken. The egg is a way by which hens give birth to baby chicks. It makes no sense to me that a chicken-centric (a new term I'm coining, and you are more likely to get a delta if you use it too) method of reproduction would come before the very creature that procreates the egg itself. I know single cell organisms originated in the Earth's oceans millions of years ago, but how on Earth would an egg come before the creature itself? Especially since, based on my understanding, chickens are the evolutionary descendants of creatures that resembled dinosaurs. There is a clear evolutionary chain that precedes chickens, so to claim that the chicken came after the egg makes so sense to me.

The chicken egg came before the chicken. The thing that laid the first chicken egg was a close relative of the chicken, but not quite a chicken.

This fits with what I’d call the common definition of what a chicken egg is - an egg with a chicken embryo in it - but if you want to claim it was a chicken-relative egg because that’s what laid it, you’d reach the opposite conclusion.

Obviously, eggs evolved before chickens, overall.
