Correction: your denominational affiliation within the religion of Christianity interprets the Bible to indicate that God created the world in 7 24-hour days. Note that nowhere in the Bible is a 24-hour day indicated or defined.
There are many other denominational affiliations, and other ways of interpreting the Bible, particularly the Book of Genesis. Even if we disagree on those interpretations, we all still believe in Christ the Savior. Right?
Well, that depends. Christ, in order to be the Savior, had to be without fault or blemish. If he had sinned in His life, then he died on the cross for Himself and wasn't qualified to be my substitute. If Christ lied or misled anyone, He would have broken a key commandment and therefore couldn't be God.(Remember "I and the Father are One. If you've seen Me, you've seen the Father") Now Jesus mentioned( you can look up the references as easy as I can) that He was the second Adam, there was a Garden, Sodom and Gomorah were real places and were destroyed, Noah and the Flood happened, etc. Now if you believe the gobbledigook about Genesis being myth or some type of moral storytelling, then Jesus was either lying or mistaken, either of which is a problem for a Christian. I read the NT several times to see if Jesus talked about a big bang, or millions of years, or pond scum or monkeys, and it ain't there. You must decide if Jesus is a liar, or He is God, but enough of the lukewarmness. If Jesus wanted to re-write the Bible He would have when He came. But the truth is, He taught from it. This talk about Bible error is blasphemy to the Savior and He will spew you out. If one reads the Bible as written, you are required to be a right wing conservative fundamentalist extreemist just to do your reasonable service. Don't try to put God in a box that you have perscribed for Him. I've heard all the reasons the Bible is false, but only when you know God personally, can you trust Him completely for the truth. The Bible is true, every word, or as Jesus said "every jot and tittle".
