Questions: Religion, man and God

hmm i got a few questions...mainly geared towards christians but anyone can answer too i guess.

My first question is on the popular debate between "Evolutionism vs Creationism." It always seems like such a huge debate going on, with some people pitting science against religion, and religion against science... What i don't understand is, "Why the fight?"

The creationists says, "God created life" while science says, "atoms formed complex molecules which formed simple cells that eventually evolved into life as we know it."

But here's the thing... If a person believes that God created man and nature, then wouldnt it also make sense that atoms/cells fall within the realm of nature? That is, if a person believe in both evolutionism and creationism, they would see evolution as merely the way God created life. In the end, this would still fulfill the belief that life was created by God; So how then do so many people view science as an opposing idea against God?

My next question is on the idea of a 'savior religion,' that is, the idea that there is only one true religion. As far as i was taught, when God first presented himself to people, he merely asked them to believe in him. I don't believe God ever gave a pronounced declaration to form any named "church" or "religion." I've always believed that religion, as an instituition, is only the creation of man to better organize themselves. And somewhere along the way people began to confuse religion for God himself; various doctrines were passed by people running the instituitions and these were passed off as God's own. I believe that churches and religions represent Man more so than it actually represents God. That being said, we all know the corruption of the Catholic church as well as others during the past (13th-18th century comes to mind). It was done by corrupt people in spots of power and represents how teachings can be skewed to represent the wishing of man. So i guess my question is: How does everyone else view their church? Do you see it as a direct representation of God's will, Mans will or maybe a mixture of both? Also, what do you feel about the general negative attitude towards gay people that christians hold? Do you think it represents God's stance or do you think its an attitude formed from human discrimination, passed on as Gods?

My next question involves a story/back ground information first. I'm a Catholic so i believe in the Virgin Mary. According to some sources, Mary has appeared all over the world. Each time she appears to someone, she'll often be seen dressed in that person's cultural garb. For example, sitings of Mary in Mexico reports her wearing traditional mexican garb, while sitings of her in Vietnam report her wearing the the vietnamese dress. In short, it is often said she appears to people within their cultural image -- perhaps to form better communication/understanding with whomever she appears to.

I believe God operates on a similar level on a much more vast scale. There are many religions out there - not all christian - that preaches similar ideas and seek to better people and society. I believe God may have presented himself in many different forms to people all across the globe. Or maybe it was the other way around; God facelessly presented himself to people throughout the globe and from there people placed various different faces on God. Which ever it is, i believe God communicates to people within their cultural system -- and does not care whether christian or not. He might appear to someone within their recognizable form of "God." In other words, i believe God is beyond image and religion and endorses all his people regardless of culture. So what do you guys think about these ideas? Possible? Not at all? Blasphemy?
