Again you miss the point. It was many speeds, and any speed all at the same time, depends on our will, and need, and God's will. It was made to respond to us![example, one star maybe was supposed to shine on earth this year, another one, just as far, maybe was not, so only the light of the one got here!] Why do you think the devil is so jealous and hates mankind so???? We were made to rule the universe with Him. He put us over this creation.
Look at the two witnesses in Rev 11, they have power, like Jesus has power over the earth, and sea, and rain, and etc!!! Jesus calmed the sea, for example. That is the sort of thing that man also was meant to do. We were truly robbed, and sold a horrible false bill of goods, by the enemy of our souls.
