_____ Is To The Earth,as _____ Is To The Egg?

The answers to this fill in the blank shouldn't be very hard to find.However,I will leave a few clues in the sentences that follow.The answer has not been proven.I just thought of this about a week ago.I feel as if most people haven't thought of this,but I doubt that I was the first to think so.I'm sure someone will know the answer and I am curious as to who the first with the correct answer will be.
Post your guesses as comments.I will do my best to announce the first correct response shortly after it is made.Your participation is appreciated.
