The planet is now a fit home for animal life. On day five God
speaks into existence all manner of sea life and creatures of flight.
The seas are to "swarm with swarms of living creatures" (ASV); this
conveys a feeling of immediacy. No long, gradual process is here
intimated; the command is urgent. The creation of birds is spoken of in
like terms: "and let birds fly above the earth...." The Creator brings
His creatures into being capable of functioning in their determined
roles. Fish are created swimming; birds are created flying.
As with the vegetation which preceded, the creatures of day five are to
reproduce after their kinds. Evolution teaches that birds are the
biological descendants of reptiles, which descended from amphibians,
which descended from sea creatures (Simpson and Beck, 1965, pp 608-
623). However, Moses says that birds and fish were created at the same
time. Once again evolution and Genesis are irreconcilable. Once again,
evening falls and morning returns, thus concluding the fifth day.
