I agree. There is so much contained in the first few lines of Genesis. It tells us of an age before this one. The earth is billions of years old but this present "2nd. age" started about 14,000 years ago with mankind coming into existance on the 6th day (6,000 years ago - a day is to the Lord as 1,000 years).
There is a lot of depth to the story in Genesis. Much more than we were taught when we were children.
“...a day is to the Lord as 1,000 years...”
Six earth days, or 6,000 earth years doesn’t make much difference to me. Time is for us, not for God. God is in an eternity that confounds our natural minds, though we give lip service to “eternity”.
