Religion: wicca and christianity?

Ok, so one religion that I have always liked is wicca. I love how it is nature-based and how they believe that the ultimate deity is a combination of god and goddess. But why doesn't wicca include all gods and goddesses? And I read in a book once that wiccans have a different name for angels and that they do believe in them in a way...is that true? and in alot of mythology, the gods and goddesses they believe in belong to a heaven of some sort and a place called the underworld (I think of the underworld as a place of punishment for being bad. Kinda like hell,but it doesn't have to be exactly like the christian hell). So can a wiccan say instead of the christian hell, they believe in the underworld as their own version of hell?What about choosing to believe in ALL gods and goddesses? Because I believe that that god isn't just male, female as well. If in christianity, god is anything and everything, than why can't god be female as well? I heard that in original christian theory, the holy spirit was considered female. I think that god/goddess is one,but also made up of many gods and goddesses because there are alot of similarities between jesus and gods and goddesses of wicca. Alot of mythology has stories similar to jesus. But anyways, I'm not trying to offend anyone with my questions so please don't feel I am trying to offend you, I am just curious to know. I honestly don't know what religion I am yet, but I don't want to be a christian, it's just not right for me in my heart. No offense to any christians, I think your beliefs are great and you should have no shame in what you believe just as long as you don't offend or try to condemn anyone with your beliefs. I really love the wicca religion and would like to find out more about it and am curious to know what they think about what I think. I would like to also get some information on taoism and voodoo. I want to know about those beliefs and rituals because I have read so much and am so confused about their beliefs so I think I should as them about it instead of making an umption because I don't want to offend anybody. Thanks for taking the time to hear me out guys!
