Young earth creationism isn't biblical. It belongs to people who are ignorant of the truth found in the scriptures. Here is what Peter says about how long we should consider one day with God:
2 Peter 3:8 - New King James Version (NKJV)[SUP]8 [/SUP]But, beloved, do not forget this one thing, that with the Lord one day is as a thousand years, and a thousand years as one day.
According to Peter one day with God is as a thousand years meaning one day with God is actually a very long period of time in human terms. So why would we argue that one day with God is 24 hours just like it is for a man? Makes no sense. The Bible doesn't tell us how old the earth actually is, but this verse in 2 Peter makes it clear that each creation day should be viewed as a very long period of time and not as a day is viewed in human terms.
I look at it this way, "with the Lord one day is as a thousand years,
and [with the Lord] a thousand years as one day."
possibly meaning that God doesn't experience time like we do... what seems like a thousand years to God is a day to us.
when the scriptures say that israelites were to work six days, of course that doesn't mean six thousand [human] years.
