Question

which came to earth first? egg or hen?​

Answer 1

Back to our original question: with amniotic eggs showing up roughly 340 million or so years ago, and the first chickens evolving at around 58 thousand years ago at the earliest, it's a safe bet to say the egg came first. Eggs were around way before chickens even existed.
