Even the rational world is biased and driven by personal motives. All hypothesis are by nature biased and fundamentally born from personal desires. Let's just say that the scientific method is the physical or logical verification of a hypothesis by experimentation or mathematical proofs.

Irrespective of religion or faith, everyone one of us live our lifes governed by a set of expected or predictable observations. For example we know that tomorrow the sun will rise and in the evening the sun will set. We know that we will be hungry sometime tommorrow and we will need to eat or that when the sun shines on trees, if it's flowers pollinate than it will bare fruit. These observable predictions lead to more observable predications, they are so consistent and such a fundamental part of our lives that we might even call them "truths". In fact if they don't consistently happen we might likely die. These rules are the premise of science and logic, they can be denied only if you lie to yourself.

Faith and religion and God is really about motivation and direction. We have to make decisions every second of every day, what we plan to do, where we plan to go and what we expect tomorrow - without religion or faith or god or ideals we are left with human desires. I do not want to live in a world where people are motivated my greed, beauty, envy and desire - a world full of atheist without direction concerned with only pleasing themselves and their personal beings.

I want to live in a world motivated by wonder, and love of something greater and better than who we are, and that might provide an explanation for all the complexity and functional completeness of nature... Whether it exists or not is really irrelevant.
