There are three stories of how the world came to be--the Tualohic, Chthonic 
and Gaeic accounts.  These are the condensed versions:

TUALOHIC: In the beginning, there was Chaos.  Into this Chaos came Tualoha,
the Creator, who imposed by her nature onto the world space, and form, and
concept.  Out of the maelstrom was born stability and light, beauty and
soul.  And it was good.  And Tualoha rested.
  Yet it came to pass that the Chaos, not yet banished, regained its hold
over the world, in the form of Chthon, the Destroyer, who corrupted the
essence of Tualoha's creation.  Tualoha saw this, and saw it was bad.  And
she banished Chthon from the world with her great light, and left it, and
thus was brought into the world forevermore the great war between light and
dark, creation and destruction, in which we are the soldiers.

CHTHONIC: In the beginning, there was Order.  And into this Order came
Chthon, the Destroyer, who imposed by his nature onto the world time, and
change, and ending.  Freed from stagnation were death and decay, destruction
and corruption, bringing with them growth and energy, the motivations that
move mountains, the mortality that strengthens.  And it was good.  And
Chthon rested.
  Yet it came to pass that the Order, not yet banished, again spread its
smothering embrace over the world, in the form of Tualoha, the Creator, who
paralyzed the workings of Chthon's essence.  Chthon saw this, and saw it was
bad.  And he loosed the world from Tualoha's grasp, and left it, and thus
was brought into the world the great war between change and stagnation, in
which we are the soldiers.

GEAIC: In the beginning, there was Life.  And this Life grew, and it spread,
and it changed, and it achieved mind.  And in so achieving, it began to
dream.  And from these dreams came Gaea, she who was Life given form and
essence.  And this form grew and changed, in all the myriad ways we see
before us.
  Yet it came to pass that within this life, which was without beginning and
without ending, there was that which longed for finitude, and limitation,
a beginning and an end.  And in so longing, it began to dream.  And from
these dreams came Tualoha, she who seals the past, and Chthon, he who seals
the future.  
  And Gaea looked upon this, and she smiled.  For she knew that in their
insistence on beginnings and endings, the gods had sealed their own, and
that their own weapon, time, is/was/will be turning against them, leaving
only Life, of which we are the students.

The Gaeic account is probably the closest to how things truly came to be, 
but that's a hard judgement to pass.
