Ruling out God?

According to an article I read recently, science doesn't need God to explain our universe, or how it came to be...

Over the past few centuries, science can be said to have gradually chipped away at the traditional grounds for believing in God. Much of what once seemed mysterious — the existence of humanity, the life-bearing perfection of Earth, the workings of the universe — can now be explained by biology, astronomy, physics and other domains of science. 

Although cosmic mysteries remain, Sean Carroll, a theoretical cosmologist at the California Institute of Technology, says there's good reason to think science will ultimately arrive at a complete understanding of the universe that leaves no grounds for God whatsoever.

Carroll argues that God's sphere of influence has shrunk drastically in modern times, as physics and cosmology have expanded in their ability to explain the origin and evolution of the universe. "As we learn more about the universe, there's less and less need to look outside it for help," he told Life's Little Mysteries.

....Judged by the standards of any other scientific theory, the "God hypothesis" does not do very well, Carroll argues. But he grants that "the idea of God has functions other than those of a scientific hypothesis."

Psychology research suggests that belief in the supernatural acts as societal glue and motivates people to follow the rules; further, belief in the afterlife helps people grieve and staves off fears of death.

"We're not designed at the level of theoretical physics," Daniel Kruger, an evolutionary psychologist at the University of Michigan, told LiveScience last year. What matters to most people "is what happens at the human scale, relationships to other people, things we experience in a lifetime."

So, I'm supposed to believe that our the earth, the perfect environment for human life just happened? One little shift, this way or that, and it just doesn't work? Sounds cold, calculating and clinical to me. Scientists can explain away God but they can't explain:

Why cat's purr...

How a bicycle works...

Why there are lefties and righties...

What causes static electricity...

Why yawning is contagious... 

I'm not trying to undermine science...our world should be studied. Just wish they'd stop trying to undermine my God.
