Some people at this point will say "but if that egg was laid by a chicken, then what came first the chicken or the egg?"
There is still no dilemma to this question.
The reason that there is no dilemma is that these people have created another dilemma in their minds.
In so doing they have redefined the question.
The question they have asked is "What came first the chicken or the chicken’s egg?
Again there is no dilemma to this question.
