Yes, to help us, to inform us. No one denies that. But it sounds like they look to science exclusively. That said, who knows how the questions are worded if 8% think there is a God. There are so many badly written surveys, and answers are soo sensitive to the slightest changes in wording...
The fool hath said in his heart, There is a God. They are corrupt, they have done abominable works, there is none that doeth good.
Psalm 14, KJV revised edition
