Did they have Noah’s arm?

Nooooooooooooooo, but they had an EGYPTIAN measurment of a cubit, that Moses used (he was raised in EGYPT, and that was the standard of measurement they used, IN EGYPT). Did God tell Noah what a cubit was? Who knows? And I’m just guessing that the measurement of Noah’s elbow to finger was far longer than 20.6 inches. (much taller and lived much longer than humans after the flood to this day)
The point is that God told MOSES that the ark was 300 cubits long. And Moses would have certainly known how long an EGYPTIAN CUBIT was, because Moses grew up, and was educated, IN EGYPT.
