If there is a Creator-God, it has used methods of creation that are indistinguishable from nature, it has declined to make itself known for all of recorded history, it doesn't intervene in affairs on earth, and has made itself impossible to observe. Even if you believe in that God... why would you think it would want to be worshiped?

Naturalism is the view that the physical world is a self-contained system that works by blind, unbroken natural laws. Naturalism doesn't come right out and say there's nothing beyond nature. Rather, it says that nothing beyond nature could have any conceivable relevance to what happens in nature. Naturalism's answer to theism is not atheism but benign neglect. People are welcome to believe in God, though not a God who makes a difference in the natural order.

For years I had problems dealing with God through religion. That is until I realized it wasn’t God I didn’t believe in, it was the religion. Be made a Xian, become an Atheist, find God, become a Deist; ah, the classic American spiritual journey...

A few years ago the Deists denied the inspiration of the Bible on account of its cruelty. At the same time they worshiped what they were pleased to call the God of Nature. Now we are convinced that Nature is as cruel as the Bible; so that, if the God of Nature did not write the Bible, this God at least has caused earthquakes and pestilence and famine, and this God has allowed millions of his children to destroy one another. So that now we have arrived at the question -- not as to whether the Bible is inspired and not as to whether Jehovah is the real God, but whether there is a God or not.

The natural is so awesome that we need not go beyond it.

Since science is essentially objective, involving the study of how things actually are, "materialism" would therefore seem to be its antithesis, since its starting point is the desire to impose upon the natural world a particular and limited way of looking at it.
