People who claim the Hebrew word yom (day) in Genesis Chapter 1 can have many meanings, usually hope there is one thing in cannot mean - 24 hours! God forbid that our Creator doesn't say what he means and means what he says. The very fact that that if we didn't "get it" after reading the first chapter of Genesis, the very finger of God spelled it out VERY CLEARLY in Exodus when He said in Exodus 20:11
“For in six days the LORD made the heavens and the earth, the sea and all that is in them, and rested on the seventh day; therefore the LORD blessed the sabbath day and made it holy."
After all, if you can't trust what God says right from the beginning of His word, why should we believe the rest of it. That's why you get falliable men trying to change the Word of God in order to use secular evolutionary long age time scales. Even Carl Sagen had more discernment then many Christians. Carl Sagan said, "The only truly intellectual dishonest position out there is the position that tries to wed Genesis with big bang cosmology." For thousands of years, Christians have held onto the truth of God's Word as the foundation for their belief in creation. Some though have altered His Word to say something very different about the origins of the universe. What are these changes and how have they affected Christianity? This is where unbiblical theories such as day age, gap theory, progressive creation, theistic evolution etc. come into play with various facets of what calls it self "christianity" All of these theories place death before sin. And that would make God a liar. Thus enter the serpent with his "Did God Really Say??" After all Satan knows Psalm 11:3 better than alot of christians and he is milking it for all its worth by undermining the foundation of God's Word - Genesis 1-11.
Psalm 11:3 If the foundations be destroyed, what can the righteous do?
By the word of the LORD were the heavens made; and all the host of them by the breath of his mouth Our Awesome, Powerful God literally just spoke things inter existance.
I think the following videos explain it best. I suggest you do the intelligent thing, and pray for wisdom. The truth truly does set you free. The bible made a whole lot more sense to me after God showed me His truth according to His Word -
