The title of this thread is both true and false. Let me explain.
In the Hebrew Bible the first creation story represents time as a spatial measure, not a temporal one. This is one of the ways in which the first creation story is unique in all of literary history written as it was, in part, as a polemic against the pagan’s conception of time. In pagan mythology for example, time was circular (think of the movie Groundhog Day and you have a pretty good idea of how the surrounding pagans viewed time). In most (all?) pagan creation stories of those times, the passage of time was cyclic and repetitive. As a consequence, actions today were of limited impact in the future. Bruce K. Waltke reminds us that these pagan myths…
… of the Ancient Near East did not conceive of time in terms of a horizontal, linear ordering of events reaching from a historical beginning to a final consummation of all things. Rather, they regarded time as cyclical, the annual reordering and revitalizing of the universe. Their creation myths were recited at annual New Year’s festivals as magical words to accompany a magical ritual in order to reactualize the original cosmology, the passage from chaos to cosmos. In mythopoeic thought time has no significance and history no meaning.
So, how did the ancient Hebrews understand time? To paraphrase Waltke, the trajectory of the first creation story is as a horizontal, non-repeating, linear ordering of seven events. It is only on the seventh that, upon the completion of the previous six, that time comes into view (specifically, God blesses time - an action not found in any of the pagan mythologies).
The scriptural basis of this interpretation is pretty compelling. To see this we can turn to Genesis 1:5: here is the relevant text from the underlying Hebrew:
“וַיִּקְרָא אֱלֹהִים לָאוֹר יוֹם וְלַחֹשֶׁךְ קָרָא לָיְלָה”
which reads “And Elohim called the light - day; and the dark he called - night.” More specifically, God does not assign a temporal measure to ‘yom’ or ‘layla’, but a spatial one. In other words, the literal text portrays yom and layla as regions of space, not a measures of time. You can read a more detailed explanation of this idea, here.
I teach a course in Genesis creation here at a local university and in my classes, I get my students to imagine that God is a metaphorical film editor in which He carefully examines and edits the first six frames of His creation movie. Accordingly, He adjusts the contents of each frame as He sees fit. When He’s satisfied, He loads the film into a cannister (do they use such things these days?) and starts the projector.
So, the title of this thread is true (God’s time is NOT measured by earth time). But I do not see a way out for the YECs until and unless their understanding of Holy Scripture is better informed by the meaning of the biblical text.
