Evidences are important.
Otherwise is God is no better than Ra, Zeus, or the Fairy Godmother, Satan is no better than ghoul, goblin, Big-Foot or the Big Bad Wolf. And angels are no better than elves or fairies.
The stories of the creation and flood are no different than other creation myths from other cultures in Mesopotamia, Egypt and India.
Belief and faith in a belief can only go so far, and is about as reliable as these myths.
Why should the Bible or any other scripture be exempted from critical analysis and investigation, when it provides no evidences beyond than literary evidence and faith? I might as well as believe in the Fairy Godmother as I would believe in God or Satan.
The evidence that the earth and the universe is older than the Bible's less than 6000 years speaks louder. That we have no evidence of global flood between 4000-4350 years ago is proof that the Genesis is wrong.
Believe me, "believing" is actually the easy part. It is much harder to not believe, because there is certain comfort in following everyone else. When you open your eyes and see that what the bible or other scriptures say and got many things wrong, then you realise you are being conned. Some people refused to see the proof, preferring the belief of supernatural than the evidences found in nature.
Don't get me wrong. There are some values in the Bible and other scriptures in regarding to the wisdom, compassion and justice in which case I can admire the teachings of Jesus, Moses, etc, but the miracles and prophecies are very hard to believe. That's why I would prefer evidences, in regarding to miracles and divine intervention, other than the testimonies of so-called prophets and messengers.
