The numbers may or may not surprise you. For the 200th anniversary of Charles Darwin's birthday, Gallup did a poll among Americans to find the current level of belief in evolution. You can find the complete survey results here.
Richard Dawkins is famous for his statement that Darwin made it possible for him to be an intellectually fulfilled atheist. Yet when Dawkins was questioned by Ben Stein in the film "Expelled" as how how evolution answers the question of existence, he couldn't do it. He punted to an assertion that aliens seeded the earth and that's how existence arose - an opinion shared by Francis Crick the co-discoverer of DNA. Of course, this explanation runs afoul of the infinite regress problem (who seeded those aliens and the ones before them?)
You have to, at some point, reach an uncaused Cause that brought about everything we know. Darwin didn't attempt to go there - instead Origin of Species starts off with several existing life forms that are already in possession of reproductive capabilities (isn't that convenient?) The question of existence isn't answered by him maybe because he knew that the options boil down to just two - matter before mind or mind before matter. And even skeptics of Christianity - such as J. S. Mill - have stated "It is self-evident that only mind can create mind."
Natural selection and survival of the fittest? Sure, we see that. Micro-evolution? Yes, we have different breeds of dogs and such. But mind arising from mindless matter, existence coming from non-existence, purpose and meaning emanating out from purposeless and meaningless stuff, and personality coming from impersonal things? No, that doesn't happen - cause and effect just don't work that way.
But a Cause that resembles all the effects we are in possession of? That makes perfect sense.
So happy birthday Charles. You certainly are a towering figure and were right about some things, but you were wrong about the most important thing.
