It could very well be that God counted himself 7 days, but that millions or even billions of years were passing.
God did not try to confuse us. YOU are confusing yourself!
When God says it is the Fifth day - that's what it is. And there was evening and there was morning - How much MORE SIMPLIER could HE have made it. EVEN the simply things confuse the wise!
Isaiah 5:21 Woe unto them that are wise in their own eyes, and prudent in their own sight.
You see, God knew there would be those that couldn't understand things in their own minds - so they create their own reasoning to things. God has it all covered in His Word. He created the world. Don't let the 'educators' trap you with their piddly little brains - trying to be more intelligent than their own Creator.
Do you believe that everything in the Bible is to be taken absolutely literally?
I don't.
