The problem is the concept of the almighty God, the omnipotent, all-knowing and always-right entity that is the creator of everything...
...If the Bible says Earth and men were created in 6-7 days, but science says Earth is 4 billion years old, then the Bible just must be right.
If he is omnipotent why did it take 6-7 days? He could have done it in the blink of an eye.
He sounds lazy to me.
