There is no possible way to read the text complete with the citation of earlier writing and conclude that the Sabbath was created to remind the Israelites of the exodus. To repeat this is false teaching and heresy. The intent is to convince Christians that Exodus 20:11 is not the true word of God so it can square with the lie of universal common descent. The question is, are you interested in what is actually written or is it your intent to continually misrepresent the Bible and pretend that the Sabbath had nothing to do with a six day creation? If you repeat something not knowing it is untrue then you've made a mistake. If you know it's untrue then you're lying. That's the distinction. We don't get to choose which verses we agree with. The six day creation violates all the laws of science, but we know it's true because God said it. It's not a made up belief, it's the word of the Creator Himself.
He seems to have bailed on you but the obscure nature of your post has me curious. The Sabbath was established during creation week, the seventh day obviously. It's always been taken to represent the fact that creation was finished so God stopped working. In Hebrews the indication is that the Sabbath rest is faith in the completed work of Christ:
Therefore I was angry with that generation,
And said, ‘They always go astray in their heart,
And they have not known My ways.’
So I swore in My wrath,
‘They shall not enter My rest.’”
Beware, brethren, lest there be in any of you an evil heart of unbelief in departing from the living God; but exhort one another daily, while it is called “Today,” lest any of you be hardened through the deceitfulness of sin. (Heb. 3:10-12)
How could we not find that disturbing, they hardened their hearts so God would not let them enter His rest. The immediate context in light here are the unbelieving Hebrews who refused to enter the promised land for fear. In judgment God swore that generation would never enter, with the exception of three, Joshua, Caleb (who they nearly killed btw) and Rahab the Canaanite prostitute that helped the spies and is included in the genealogy of Jesus.
What that could possibly have to do with the laws of science I don't know but there is a premise of the faith in creation:
I believe in one God,
the Father Almighty,
maker of heaven and earth,
and of all things visible and invisible;
And in one Lord Jesus Christ,
the only begotten Son of God,
begotten of his Father before all worlds,
God of God, Light of Light,
very God of very God,
begotten, not made,
being of one substance with the Father;
by whom all things were made; (Nicene Creed)
That's the first three stanzas of the Nicene Creed, Catholics, Orthodox and Protestant churches will tell you that at a bare minimum, you believe this, or you are not a Christian. In the three opening stanzas you have a confession that Christ is God the Son, sandwiched between two confessions of God as Creator. Theology does not predicate its core axioms on laws of science, it is predicated on truths that transcend everything else, the doctrine of Creation is one of those doctrines.
Creation is essential doctrine and we do well to continually remind Darwinians of all stripes, Theistic or otherwise, you either believe it or you are not a Christian. Indeed we vary on some of the details and I often clash with other Creationists on the timeline and such but to worship Christ as Savior and Lord is to worship Him as Creator. Theistic Evolutionists are strangely silent on this particular point of doctrine.
Grace and peace,
Mark
