I know you have heard it before but which can first chicken egg or something else

I am christian, but I believe that it was actually an egg that came first

If you are a Christian, the Bible says that God made animals, not millions of eggs, so the chicken. If you are a scientist, there were prototypes that evolved into the first chicken, so the egg. Depends which way you look at it. ;)

Egg cos dinosaurs laid eggs

The egg. Most likely the egg because there once was no chicken. Scientists believe that a mixture from a turkey and another animal made an egg and made an animal that we named Chicken. So the egg came first.
