I maintain that these were normal days.
It's your perogotive to maintain whatever you want to maintain. It's no skin off my nose.
I'll maintain that a normal day refers to a twenty-four hour day of explicit duration. However "yom" sometimes refers to indeterminate periods of time. That's just the reality of how the ancient Hebrews understood things.
BALANCE: you have yet to prove you are the standard...
Never claimed to be, so this comment is nothing more than obfuscation aimed at derailing the discussion.
A historical/grammatical approach does not rely on "finding balance." It relies on the normal meaning of words and their usage by the same author.
It requires both by necessity. Scholars utilize the historical records preserved ancient civilizations to better understand how primitive languages functioned.
