Since I wasn’t there at the time, and can’t find anyone who was, or who knows anyone who was there, other than God Himself, I’m just going to put this on my list of questions to ask God when He gets around to asking me if I want to know anything.
This is on a long list of things that I believe God did and continues to do, but I don’t know how.
I wonder whose faith would be shaken if it turned out that “morning and the evening” were something other than 24-hour periods. I always had the impression that time was not something that really meant much to God, but as with so many things in my faith life, I stand to be corrected (by God, not necessarily by others on this site).
