The bible teaches that the Earth was created
in 6 days by God. Fish and birds were created
on the fifth day, then animals and humans on
the sixth. God said that all this was good.
Literalists and creationists
believe this story word for word.
Other Christians are more open to the interpretation of the Bible as
not completely accurate. They believe that the Bible is not answering
the question of 'how' the world was made, but 'why' God made it.
Therefore the Bible story doesn't have to stand up the scrutiny
because it wasn't intended as a guide for how the universe began.
So Christians who believe that God
created the world are actually
underlying four key things: 1)
Everything was created for a
purpose, 2) Life's beginnings were
not accidental, 3) Humans are
different from animals 4) The world
was basically good
