Quote from : The Martian Chronicles Book

They knew how to live with nature and get along with nature. They didn't try too hard to be all men and no animal. That's the mistake we made when Darwin showed up. We embraced him and Huxley and Freud, all smiles. And then we discovered that Darwin and our religions didn't mix. Or at least we didn't think they did. We were fools. We tried to budge Darwin and Huxley and Freud. They wouldn't move very well. So, like idiots, we tried knocking down religion. We succeeded pretty well. We lost our faith and went around wondering what life was for. If art was no more than a frustrated outflinging of desire, if religion was no more than self-delusion, what good was life? Faith had always given us answer to all things. But it all went down the drain with Freud and Darwin. We were and still are lost people.
