I'd say both, but then billions and billions of years ago the sun shined and single celled animals grew, reproduced, died, then deposited unceremoniously into crooks, crannies, and dry sea beds all around the world where they lay covered by tons and tons of rock and earth, under incredible amounts of heat and pressure, until each one of their tiny little bodys were converted to oil molecules.
Then along came man who built the automobile, and rather than have it sit in his driveway, unable to move, he built oil wells, refinerys, and gas stations, to provide himself with expensive gasoline. Man could at last venture out beyond his own garage.
Now that man could travel he found himself in need of recreation so he built poolhalls in most major and medium sized cities and commuted back and forth in the automobile powered by the single celled animals, heretofore mentioned. Life was good for man, but not so for women. They had to stay home and keep man's tip shaped.
Now what's this got to do with faith? Simple. Just continue to believe the sun is going to shine tomorrow.
