What if 7 days to God is 7 billion years to us?

Actually, the bible says essentially the same thing:

2 Peter 3:8 - But, beloved, be not ignorant of this one thing, that one day is with the Lord as a thousand years, and a thousand years as one day.

Thanks, I was wondering where to begin searching because I know we (LDS) believe that a day to Heavenly Father is a thousand years to us.

You have to remember context. I think the first chapter of Genesis is clear that a day is what we think of us a day. Otherwise, why would it be repeated so often?
