[WhySoSerious?]

I have two questions here...

Lately, I have just been feeling especially curious about trying out some various sorts of religions. I despair a lot over the thought of death and the 'order' of the world, so my boyfriend has suggested to me a couple times that I go to a church. I am considering it, but the problem is I just don't believe in god.

So I was wondering, is it possible to attend church or have some form of religion if you do not believe in god? I'm not really looking to believe in god, I don't think I can, but I'm looking for something. I just want to know if it's even possible for me to try out different religions without believing in a god, (at least not one like the Christian God or Allah).. or if I should forget about it. (Would it be offensive to go into a Christian church knowing that I will never believe in their God, but wish to take part in there religion, for example?)

Secondly, I was wondering what sorts of religions might be out there which would be... better suited, for someone who doesn't really believe in an omniscient God? I don't really know many religions, I mostly hear about religions when reading about extremists or the right-wing disadvantages of it in books and articles... so I want to see more than just that.

A thought which may be easiest to answer as well: Which is the most "liberal" religion you know? (I'm not over eager to have to completely reform my dress-code or overall lifestyle...)
