Geeeeee .. I didn’t know “sewing” needles were invented before Adam and Eve came on the scene.
The Amplified Bible says that GOD “For Adam also and for his wife the Lord God made long coats (tunics) of skins and clothed them”.
Therefore, Adam and Eve did not sew fig leaves together to clothe themselves.
Genesis 3:7 And the eyes of them both were opened, and they knew they were naked;
And they sewed fig leaves together, and made themselves aprons.
God had Moses write this.
Thus the first lesson that it takes a blood offering to cover sin. The leaves would not do, there was no blood offering.
