It’s funny when you think that the first thing they think of when it’s comes to knowing good from evil is....nakedness! How ridiculous!
There are umpteen tribes who go around completely in the buff (in hot, humid countries) and don’t think a thing of it! It’s not something that humans find naturally wrong. It always seems to be colder countries that find public nakedness abhorrent. Funny that!
its just our culture which designates what is sin and what is not.
For instance, adultery to the ancient Hebrews was only if a man, married or single, had sex with a married woman. If a married man had sex with a single woman that was not adultery. That was not a sin to them.
Boiling a Kid in it’s mother’s milk was a sin to them!! “Sinning” is cultural not absolute.
