There is no single "intelligence" or "reasoning capability." Intelligence and reasoning covers a spectrum from the severely mentally retarded to super geniuses. Which ones were given God's reasoning abilities?

Adam and Eve (who were created in God's image, not given the fullness of God's intelligence. They weren't gods, so they didn't have the benefit of omniscience). Problems with intelligence and reasoning are a result of degeneration which was the result of the fall.
