Warning: doing this exercise can destroy, diminish, but also enhance or refine your beliefs. Nevertheless I dare you to do it. Please consider this: how weak would your beliefs be if they can be shattered by a mere text on the 'net?
Step 1: answer the poll. Please select only the things you litterally believe in. No metaphors here.
Also, you should interpret "to exist" quite narrow, as "existing independently from human convictions, ideas and faiths". This because you can say that, in a way, Little Red Riding Hood "exists", because she influences a lot of people and without her, a lot of books and plays wouldn't exist. But Little Red Riding Hood is a figment of human imagination and wouldn't exist without humans having created her and telling/writing/acting/singing about her.
On the other hand, you should interpret "God" as broad as possible. "God" represents any god, godess, gods or godesses in any number or combination. Don't leave the thing unchecked only because you don't attribute a gender to God.
Step 2 (warning here): Look at the things you didn't check. Do you sometimes claim you do believe in them? Because then you're lying. You can of course wiggle around it, with saying you believe only metaphorically, but still you're saying "I believe in..." which can be taken litterally. If you believe God can read your thoughts, He's going to know you're insincere or only repeating the Creed out of custom or habit.
Step 3 (danger here! proceed with caution): Look at the things you did check. Isn't there anything that contradicts another thing? Or itself? Or common sense? Or observation? I'm not telling you have to follow things like observation - I'm telling you you should at least think a bit about it.
