You may have misread my answer: I was not declaring that "egg" meant "ovum", I was saying that other people were. The "egg" per Wikipedia, is the vessel that contains the developing chick. In that regard, it's analogous to the uterus. Indeed, assuming we take "which came first, the chicken or the egg?" to mean "...or the chicken egg" (otherwise it's just a silly question, as dinosaurs had eggs), then we can make the analogy to "which came first, the human or the human uterus?" That should clearly be trivial to answer: the first organism that we could call a "human" must have started developing before her uterus did. So the human came before the human uterus. I'm saying that this is equivalent for a chicken egg. Since the "egg" is created 100% by the mother, albumen, yolk, shell and all, I'm saying it "belongs" to the mother, in the same way that a uterus belongs to a mammal mother. It's all her own cells. Therefore, the first "chicken egg" had to be the one laid by the first chicken. So it comes after the chicken.
