Evolution only describes a mechanism. Explaining the parts of an engine and how they work together to run a car doesn't tell you who built it. We have zero evidence of life arising from non life, which is the entire basis of naturalism. Maybe the reason early man looked at creation and posited a God, is because God designed us that way. Science isn't bad, but it can breed a startling amount of arrogance and pride. And the more prideful we become, the more we put ourselves in the place of God. And the more we try to push him out of creation and explain him away. Take the story of Lucifer. He lived in the presence of God and yet became so prideful that he thought he was better than He who created him. How much more for us who have never seen God face to face? The bible talks about this. http://bible.com/100/rom.1.19-23.nasb because that which is known about God is evident within them; for God made it evident to them. For since the creation of the world His invisible attributes, His eternal power and divine nature, have been clearly seen, being understood through what has been made, so that they are without excuse. For even though they knew God, they did not honor Him as God or give thanks, but they became futile in their speculations, and their foolish heart was darkened. Professing to be wise, they became fools, and exchanged the glory of the incorruptible God for an image in the form of corruptible man and of birds and four-footed animals and crawling creatures.
