The Chicken vs. The Egg

I had a hard time falling asleep last night and I started to think about that age-old question "what came first, the chicken or the egg?" It seems obvious that the egg predates the chicken. Why? The first animals to pull themselves up onto the land reproduced with eggs. Birds lay eggs and they must have developed after the first amphibians. Ergo the egg must have predated the first chicken, which likely developed from a cross-species hybrid or simply mutated from the Grey Junglefowl to form a distinct species of bird.

If you go the religious route chickens were created on day five.

So either way chickens predate eggs.

Wait, what? This is what happens when you blog and talk on the phone at the same time. If chickens evolved the egg predates the chicken. Under creationism chickens would predate eggs (as eggs of any animal are not specifically mentioned as being created at the same time in Genesis).
