“But do not forget this one thing, dear friends: With the Lord a day is like a thousand years, and a thousand years are like a day.” 2 Peter 3:8 NIV
1 day to the Lord is LIKE a thousand years. Does it mean that 1 day is equal to 1000 years. The text says ‘one day is like [or as] a thousand years’—the word ‘like’ (or ‘as’) shows that it is a figure of speech, called a simile, to teach that God is outside of time (because He is the Creator of time itself). In fact, the figure of speech is so effective in its intended aim precisely because the day is literal and contrasts so vividly with 1000 years—to the eternal Creator of time, a short period of time and a long period of time may as well be the same. Meaning, a day to the Lord may range from 1 day to billion years.
Having said the above.
Did God creation took?
a.) 6th days (Human time)?
b.) 6th days(God’s time meaning it could be more than a thousand even million years)?
