The effigy of Adam & Eve with fig leaves is a modern adaptation of naked people because we are too conservative these days to accept that we never used to need clothes.
So in short. They never actually had fig leaves. They almost certainly had a lot more hair than we would like to think, and were probably A-sexual.
The Bible doesn't mention fig leaves.
The term "snack" didn't exist when the Bible was written.
The Bible doesn't mention an apple, just a forbidden fruit.
And last, but not least, the Bible is a book of myths.
