Evolution, in the context of science, does indeed have a very deep meaning. It is quite possibly the biggest idea ever in biology. It explains the whole of life on earth in all its diversity, complexity and beauty. It goes a long way towards describing the origin of life. For all we know, it probably explains life wherever it arose in the universe. It's as good as that. But it is not a religion. Evolution's feet are rooted firmly on the ground among masses of solid evidence, not up in the sky or beyond, the domain of some inexplicable super-being running the show. On the other hand, evidence is the enemy of religious faith. The more evidence you have, the more shaky the foundations of faith become. That is why religion has felt threatened by science for thousands of years. Of course, even the most devout believers rather like the science and technology (all of it evidence-led, inconveniently) that makes the modern world what it is, so they try to find some accommodation with science ("I do believe in evolution but God kick-started it and runs it"). Actually, Richard Dawkins called evolution the greatest show on earth. And it doesn't even need a stage manager.
