On the fifth day, God speaks life into the waters and sky. The word 'abundantly' shows God's generosity — He does not make just a few creatures, but fills creation with overflowing, teeming life.
Memory phrase: God filled the water and sky with life.
Talk about it: Can you name some creatures that swim and some that fly?
Prayer: God, thank You for every fish in the sea and every bird in the sky. You love living things!
