This age-old question really has a simple answer. Attempts to answer it, however, and attempts to get around implications of the simple answer are often quite convoluted.

Honestly, I feel that it is the chicken. If the egg was the first then there wasn't anyone to take care and hatch the egg, then it wouldn't be able to survive. That's why I am quite sure that the chicken came first. Otherwise, we wouldn't have an animal that we call chicken.
