Excerpt: ‘Celestial bodies allegedly formed when gas and dust particles coalesced in a process called accretion, forming protoplanets or planetesimals. Accretion theory is part of the nebular hypothesis of solar system formation. Experiments have not demonstrated that accretion occurs. God created heavenly bodies by His spoken word (Ps. 33:6), not a process’
