My experiences and feelings about God are confusing and difficult to explain, but I will try.
When I look at religions, (all religions) I see a common theme of people wanting to know that there is more to life than just this. More than just a random sequence of procreation and death with nothing guiding it. They don't like the idea of chaos.
I've also always seen a tendency for cultures to credit things they don't understand to some mystical being (IE cultures worshiping a Sun God that makes the sun come up or a woman who is released from the underworld every spring to make the flowers grow). Every culture for all written history has its Gods, Goddesses, Angels, Prophets... all of which are meant to explain what is unexplainable to them.
Also, another interesting point is that as more things became explainable by science, there came a (slow) movement from Polytheism to Monotheism.
Then there are cultures like the Native American cultures who believe that all things are connected and have a spirit. Or the cultures who believe in reincarnation. (An idea which I personally like)
I've studied all of these things, I suppose always trying to understand my own feelings about religion, but all it has done is lead me to create my own kind of idea about the Universe that doesn't mesh with just one religion.
I was raised in a Protestant family, church on Sundays with the Grandparents and what-not. Even then I was the child asking things like 'If God created Adam and Eve... who made God?' and 'How can he have 'always existed'. The idea of 'infinity' only made sense to me when I put it in the context of God being created by humans and not the other way around, which disturbed me because it went against everything I'd been taught.
THEN I read this book called "Many Lives, Many Masters". This book threw me for a loop, essentially declaring a kind of Reincarnation meets String Theory concept. (Awesome book by the way, if you like that kind of stuff)
I also attended a Franciscan University (because it was in my home town) and learned a lot of Franciscan teachings.
All of this, in conjunction with scientific theories has lead me to believe a few things in 'my' religion:
1. There is no robed 'man' sitting on a throne in the clouds dictating how things are going to progress. There just isn't, thats crazy.
2. All things are connected. Events, people, animals, things... they all serve a purpose.
3. Nothing can either be created nor destroyed, they simply change. This includes life and what we call 'soul' or the essence of who we are.
4. 'GOD' is an all encompassing word for how all of these things come together. (Some equate God with Love)
5. Our 'essense' and our 'purpose' is to learn. Each life that we have is meant to teach us something else. Many reincarnation theories say that we choose when to come back to 'life' and what we will be trying to learn while we are here. It also claims that many 'souls' choose to come back in groups, so that perhaps a friend that you really bond with was someone you knew in a past life and that the dynamics (teacher vs student) remain the same.
6. The people who are here to learn the same things as us have a similar 'vibration' or essense about them. (This is where String Theory becomes fun) We will be drawn to them and have things in common. They are fellow journeymen on the same quest so to speak, which gives rise to the term 'soul mate'.
7. Situations will repeat themselves with a common theme in your life until you 'conquer' it and progress to the next situation. All of them will be meant to teach you whichever concept you chose to perfect in your life when you chose to return: IE: Loyalty, Patience, Love, Honesty, Integrity, etc etc. (This is actually also mentioned in some Astrology books (another kind of religion). A good one is the intro to Love Signs of the Zodiac, which says that each sign is here to learn a specific thing. (A good scientist doesn't discount anything without examination!))
Its difficult to really explain these ideas fully, but maybe these will give you the jist.
