Do you doubt that Zeus exists?

In the article  here Gary Gutting does something really cool. He gives you the chance to defend the belief that Zeus exists, in an intellectually honest way, against some reasonable objections. The subtle trick is you may or may not realize you have defended your own belief in your own god the same way.
   The really interesting thing is you are fairly certain that Zeus does not in fact exist, but you have successfully defended the possibility. Do you feel that you have successfully defended your own belief? Are others fairly certain that you are wrong?
