EDIT : It seems as no one understood what i was talking about and maybe its my fault for not elaborating . I always thought chicken was a metaphor for this paradox and not really meaning chicken as a specific spiece . So my question is how did the ancestor of chicken came to be if it was born (egg) wouldn’t it need a parent or if it was a parent (chicken ) woudn’t it need to be born ? Or did all the creatures start out as bacteria and climbed out from ocean through evalution if so why isn’t any new species being born this way or am i missing something ?
Fish, arthropods, etc, had eggs millions of years before chickens.

Dinos (
within the arthropods) are an easy example.Edit: correction
Aren’t all dinosaurs chickens ?

Afaik, is the other way around. All birds are dinosaurs, but there are non-avian dinosaurs as well.
