Thermal underwear?
I assume you are joking
I was joking
Of course the skins may have been used much earlier but why would man go to the trouble of raising sheep for the skins and throw away the meat?
They wouldn't.
What we have to remember is that a lot of the Bible consists of myths, legends, campfire tales, folk tales etc. passed down from generation to generation.
You can tell a lot about the society that the story comes from when you consider the contents of the tale. Most of the early material in the Bible came from a nomadic society, and this is reflected in the texts. Nomads always have 'home bases' along their traditional pasturage routes, all nomadic societies have small villages and all nomadic groups have/had some form of agriculture. The males fo nomadic groups do not discuss growing crops because itis seen as woman's work or work for weak males.
Look at part of the story in Genesis 3:
14 So the LORD God said to the serpent, "Because you have done this,
"Cursed are you above all the livestock
and all the wild animals!
You will crawl on your belly
and you will eat dust
all the days of your life.
15 And I will put enmity
between you and the woman,
and between your offspring and hers;
he will crush your head,
and you will strike his heel."
16 To the woman he said,
"I will greatly increase your pains in childbearing;
with pain you will give birth to children.
Your desire will be for your husband,
and he will rule over you."
17 To Adam he said, "Because you listened to your wife and ate from the tree about which I commanded you, 'You must not eat of it,'
"Cursed is the ground because of you;
through painful toil you will eat of it
all the days of your life.
3:17 Is an explanation to explain to the group why people have to work so hard, why does man have to work the land, it makes sense to them.
3:14-15 Explains mankind's natural revulsion to snakes.
3:16 Explains why childbirth is so painful. (So women would have us believe
)
These are just tales invented beside campfires by an ancient people to explain why things are they way they are.
