One could say the universe was created in 7 days.
A day is one rotation of the world.
How is it that God created some of these things when there was no globe in which to register this amount of time.
The bible also says that 1000 years are not even a day to god.
If god was the only one around then time was mostly on his own watch, most likely that is.
So no I don't believe the whole 7 days thing.
