Here's a link to a page showing dozens of ancient languages that all use the word Sabbath (rest) for identifying the seventh day of the week. If the Babylonians had Sabbath as the name of the seventh day and they were in existence before Abraham was given the promise, then this shows that the Sabbath Command was indeed given and kept since creation. There is no other way all these civilisations would have named the seventh day Sabbath (rest) if it wasn't so from the beginning.

Proof that the Sabbath was indeed created for mankind and not the Israelites as some wish to think...
Then the sabbath can't be a special issue with Israel as Moses states. The Bible winds again.
29 See, for that the Lord hath given you the sabbath, therefore he giveth you on the sixth day the bread of two days; abide ye every man in his place, let no man go out of his place on the seventh day. Ex 16
16 Wherefore the children of Israel shall keep the sabbath, to observe the sabbath throughout their generations, for a perpetual covenant. Ex 31
2 Speak unto the children of Israel, and say unto them, When ye come into the land which I give you, then shall the land keep a sabbath unto the Lord. Lev 25
5 And Moses called all Israel, and said unto them, Hear, O Israel, the statutes and judgments which I speak in your ears this day, that ye may learn them, and keep, and do them.
2 The Lord our God made a covenant with us in Horeb.
3 The Lord made not this covenant with our fathers, but with us, even us, who are all of us here alive this day.
4 The Lord talked with you face to face in the mount out of the midst of the fire,
5 (I stood between the Lord and you at that time, to shew you the word of the Lord: for ye were afraid by reason of the fire, and went not up into the mount
saying,
6 I am the Lord thy God, which brought thee out of the land of Egypt, from the house of bondage.
7 Thou shalt have none other gods before me.
8 Thou shalt not make thee any graven image, or any likeness of any thing that is in heaven above, or that is in the earth beneath, or that is in the waters beneath the earth:
9 Thou shalt not bow down thyself unto them, nor serve them: for I the Lord thy God am a jealous God, visiting the iniquity of the fathers upon the children unto the third and fourth generation of them that hate me,
10 And shewing mercy unto thousands of them that love me and keep my commandments.
11 Thou shalt not take the name of the Lord thy God in vain: for the Lord will not hold him guiltless that taketh his name in vain.
12 Keep the sabbath day to sanctify it, as the Lord thy God hath commanded thee.
15 And remember that thou wast a servant in the land of Egypt, and that the Lord thy God brought thee out thence through a mighty hand and by a stretched out arm: therefore the Lord thy God commanded thee to keep the sabbath day. Deut 5
