And how long were those days? In the bible it says "each day is (to God) as a thosand years (to man)". How could the first "day" only be 24 hours when there wasn't even dark and light yet? "Day" as defined from earth is very different than one from Pluto. Where does God live? That would determine how long his "day" is. Plus, the sun wasn't even created the first day, so how was he measuring before he created the sun?
By the way, I am very religous. I believe in the Bible and that Jesus Christ is my savior and the son of God, but I also believe that God follows the laws of Science....because there is thruth in ALL things. I believe that God is capable of miracles because he knows science and controls the very elements.
