Apparently, you think that you need that to be true, so you hunker down and insist that it is. That's the kind of reality creation - spin -that characterizes religious thought.The bible doesn't define what a day is to God, just that it's an indeterminate amount if time.
"God called the light Day, and the darkness he called Night. And there was evening and there was morning, the first day." - Genesis 1:5
This is why we don't let Christians tell us what their bible says, let alone what science is. You have no commitment to truth or reality.
