Error consists of fabricated stories, like molecules-to-man-evolution, old-Earthism, big-bang, relativism, natural-human-goodness, biblical-error stories that are made up to explain creation without the Creator and that are based on rationalizations and arbitrary assumptions like naturalism (no God), materialism (no God), uniformitarianism (no Flood) as opposed to real experience of being led by Jesus, the Creator. It's as simple as that.

Lying stories are often made to sound like they are reasonable or scientific, but they are mere fabrications, that is, lies. The ultimate source of all lies is Satan, and the human mind is deceitful and desparately wicked since the fall of man that brought mankind into slavery under Satan. Every teaching the does not proceed from the Mouth of God is a lie. Only God can be trusted to reveal His Truth to us. God reveals through Scripture, through apostles, through the members of the Body of Christ, through prophecy, through creation, and through many other means.
