Rabbi Jeremiah asked

In one of the Platonic classes, the rabbi said that many times questions in the Gemara are intended to clarify a principle, and they themselves will not really happen, like a rain of wheat, etc.
If so, Rabbi Jeremiah asked, “Is one leg of the chick inside fifty cubits and one outside fifty cubits?” This sounds like a question that clarifies an important principle even though the chances of it happening are zero, and why was it really taken out?
Thank you very much, Your Honor! “Who will not be afraid of the Nigerians who will flee before you?”
