But again, why is our world so consistent, & orderly.
You conclude orderly from a 7 day week? So I may conclude the opposite since the number of days and the months don't fit into a year?
The months period (either of them) aren't an even number of days long.
Our calender has been shoved and tweeked to work ok with the day,year and month (lunar cycle) that we have. Though we have chosen to ignore the moon now since it was only a comparitively minor matter even before today.
The seven days is clearly from a combination of numerology (and the Bible didn't originate that, I don't think) and the about 28 day lunar cycle (it is NOT by the way 28 days). There is nothing special about it.
The only order that we have is the fortuitous evenness of solar output, day and year behavior. However, that is only just even enough for now. If it wasn't we wouldn't be here would we?
I think that something else would be though.
