Wicca

Wicca is a Religion that beliefs in one God and one Godess.
The wicca isn't a satanic religion and the most rule is that if you don't do a bad things, you can do all things that you want..
The wicca's adept name are Wiccan and, when they prayer, they do a circle for protect theyselfs.
In the circle is forbidden move counterclockwise.
They revere the nature in all form and they beliefs in the reincarnation.
I think that is a very good religion and that they are a very positivity people.

nice work, this is a tricky entry because you used both first and third person. 

My suggestions:

Wicca is a religon that believes  OR    people who practice Wicca believe (which is more appropriate).

Wicca isn't ( you don't need "the" at the start ).

the most " important" rule 

when they pray (prayer is a noun, pray is a verb)

they make a circle to protect themselves 

in the circle it is forbidden to move 

Wiccans revere nature in all forms and they believe in reincarnation ( belief is a noun and believe is a verb). 

I think Wicca is a very good religon and they are very positive people. (positive is an adjective, positivity is a noun) 

Good job!
