Chicken vs. Egg

[JcX]

The egg, obviously. Dinosaurs laid eggs, and I think it's quite obvious that dinosaurs were before chickens... So, there were eggs before chickens

 

A nice play with words. Since Wizard didn't mention whether it's chicken egg or dinosaur egg.

By the way, does dinosaur really laid eggs?

Is there any scientifical proof?

What I know is researches from the skeleton left behind, and the scientist deduced all these stuffs.

There are literally hundreds of fossilised eggs left behind from the dinosaurs, from all the ones that didn't hatch for whatever reason.
