What came first egg or hen?

Actually the Rooster and then the Hen as it takes those two to make the egg

Dinos reproduced using eggs, right? Dinos turned into birds. So egg first. But you'd never be able to point at a moment in time and say, "See? Right there is where it stopped being the last thing, and started being the next thing..."

Bible says bird before egg.  And who can argue with theBible!
