No. Evolution is a scientific theory. It has nothing to do one way or the other with the concept of God. I know a number of people who accept the mountains of evidence that underlies the Theory of Evolution who are quite devout. It is a fallacy to equate evolution with atheism.
Their view--If man didn't do it, then it must have been done without any outside help, because to imagine ID is to admit there is a Grand Designer--i.e., God. Those who feel superior to deluded believers in an Almighty designer prefer to espouse evolution as the only possible "scientific" explanation. Just the fortuitous coming together of organisms, which like living pieces of a puzzle, rejected each other until finally, out of the millions/billions of possibilities they, like true lovers, finally found each other and began the long, long road to becoming the intricate universe we know today.
Cosmology and Evolution are models that describe the origin of the universe and the diversity of life here on this planet. And it is not just a "fortuitous coming together".
