The possibility of life beyond the Earth in no way challenges my biblical faith. I hold to a robust biblical cosmology. That does not mean that I must embrace an ancient mythical cosmology of a flat earth with four corners. The Psalmist has cried out that the heavens declare the glory of God (Ps 19:1). Likewise, the apostle Paul declared that God‘s invisible attributes are revealed in creation (Romans 1:20). Another way of saying this is that God is revealed in science. All truth comes from God.
