Why wouldn't an all powerful God "craft" another universe? He can do it all day long if He chooses, and I'm sure He has and is! We limit Him because we have limits. He does not! The fact that we have a book, read very little.. about our human history.. of man isn't proof enough? The book goes back to the beginning of mans knowledge of human life and it's beginnings. People WRITE THAT STUFF DOWN!! Then centuries later, the Jews kept meticulous records of everything including the 7th day, why do you think they keep it?! BTW, the 7th day is not a "Jewish Sabbath" as many say, it was given to ALL men at creation, to keep us close to our Creator. Again, They are known for keeping impeccable records that's why they keep Gods holy day.
