Don't sell it short; this planet is pretty special to Him. It's the one to which He sent His Son to die in order that sinners could be saved by His grace, reconciled to Him for eternity, rather than spend it apart from Him in the outer darkness of hell, as we truly deserve.
Insistence on confining the God's "yom" of creation to one rotation of this ball of mud implies that the Almighty had no way to measure time before he created Earth and set it to spinning.
Or, it simply acknowledges that He wrote His Word for the benefit of mankind (whom, by the way, He created in His own image). Furthermore, it's entirely conceivable that, prior to even creating this special planet in His seemingly infinite creation, He already decided a day was a day, and "in the beginning" He put time in motion (for us and the lesser things in His creation).
How arrogant, prideful, and self-centered is that?
Certainly no more so than to insist when He says one thing to us, He means something else entirely.
"...one day is with the Lord as a thousand years, and a thousand years as one day."
Which is to say He is not bound by time as we are. He is completely outside the realm of time. Time did not exist until "the beginning" of His creation. Which is another reason to be sure that, when He says it took 6 days to create His creation, that's what He meant.
Ladies, this comment epitomizes the geocentric and egocentric (self-important) tunnel vision that, IMHO, has cost the cause of Christianity immeasurably... :-(
And I praise Him for that and have gratefully accepted His marvelous grace!!!
But Jesus wasn't sent here because this planet (or the men-in God's [spirit] image who inhabit it) was/were "pretty special to Him" .
Jesus Himself said that He came "to seek and to save that which was lost".
IOW, God sent his Son here because mankind sinned -- not because this planet or its inhabitants were created any more "special to Him" than any of the rest of his mighty works.
As I said, claiming that this planet (or you or I) are "special creations" is the height of prideful hubris. What right have we to insist that nowhere else in God's vast created universe did he place beings in His own image -- or to insist that, if they were created, that they also sinned?
Being a sinner doesn't make me "special". Being saved by God's grace most certainly does...
