Julia,

First you have to find the problem with the light source that Ash hinted at.
You can read about the light source here:
http://povray.org/documentation/view/3.7.1/35/

When you have fixed it you can (just for testing) remove the whole sun sphere
and remove all your ambient statements.

Now you should be able to see shadows from your light source (because the opaque
sun sphere is no longer there to block its light).

Thereafter you can bring back your sun sphere and study the the looks_like
example here:
http://povray.org/documentation/view/3.7.1/40/

If you still have problems you may come back here and show what you have tried.
(But please indent your code better so that it is easier for us to read your
code.)
