So what you're saying is that question should have been: which came
first, the lizard (or fish) or the egg? :)

Well, technically, the "egg" goes back to our days as single-celled
organisms (bacteria, et al).

Irrelevant and incorrect.

(a) The chicken-and-egg debate is referring to chicken eggs -- not the
eggs from any earlier organism. Otherwise, the whole thing is trivial.

(b) Bacteria don't have eggs. Eggs are a byproduct of sex. Bacteria do
not come in male and female -- this simply divide. No sex -- no eggs.

Since then there have been refinements, such as eggs that could become
multi-celled organisms*

I think the semantic hair the panel split was that it's not a chicken
until the thing coming out is a chicken, and before that it's something
else. And the determination is that the parents of the first chicken
weren't chickens, genetically speaking.

But their eggs were chicken eggs, otherwise they would not have
developed into a chicken. So I think you just proved that the eggs
came first.
