Can someone tell me what came first the chicken or the egg?

The egg came first. Dinosaurs and other reptiles were laying eggs long before the chicken evolved. Not to mention insect eggs, amphibian eggs, fish eggs....

It must have been the rooster or the egg wouldn't have hatched

Arent fish eggs called caviar... Hate that stuff eww.... ?Anyway back to the point, yeah but if chickens evolved from dinosaurs where did dinosurs come from cause the first amoebas replicated by division therefore no eggs... So in other words eggs didn't come first.... Or did they?

Fish eggs are only caviar when produced by a sturgeon. Other than that they are 'roe'.

Of course the eggs came first. Single cell creatures (such as amoeba, prokaryotes, eukaryotes) evolved into multi-celled creatures. Over time these evolved into things like fish and plants. Fish lay eggs, so the eggs came first. Some multi-celled creatures colonised the land and became plants (no eggs there) or insects (eggs again). Later fish colonised the land, first becoming amphibians (eggs), then reptiles (more eggs), then dinosaurs (even more eggs). Birds evolved from dinosaurs (yet more eggs) and some of these birds evolved into modern-day poultry.

The defence rests.

On a serious note;
The egg came first.
It was laid by a lesser evolved creature. The reason for this is that most mutations (that has an effect other than cancer) takes place in the ovaries/testicles when the body cells are split into gender cells (with half the cromosomes).
So, mutations in the hen's (or dinosaur's, reptile's or creature of choice's) ovaries will result in a slightly different creature inside the egg while mutations inside the egg won't change much, except maybe killing the unfortunate creature.

The chicken came first, ever seen an egg lay itself.

The egg came first, ever seen a chicken hatch from anything except an egg?

Well..everythinv came from blobby little bits of life in the beginning, right? Don't cells look and behave more like eggs?

Absolutely, who ever heard of a chicked-shaped ameoba?
