the answer to the persistent question, What is the purpose of the universe? is quite simply: There is none. - Alexander Rosenberg

If we can't have religion, we need a substitute that is as much like it as science can provide. Enter secular humanism, a doctrine, dare I say, "designed" to do this job. It hasn't worked (...) Scientism recognizes that the ambitions of the secular humanism are unattainable.

Here is a list of some of the questions and their short answers (...) The interesting thing is to recognize how totally unavoidable they are, provided you place your confidence in science to provide the answers

Scientism starts with the idea that the physical facts fix all the facts, including the biological ones. These in turn have to fix the human facts—the facts about us, our psychology, and our morality. After all, we are biological creatures, the result of a biological process that Darwin discovered but that the physical facts ordained. As we have just seen, the biological facts can't guarantee that our core morality (or any other one, for that matter) is the right, true, or correct one. If the biological facts can't do it, then nothing can. No moral code is right, correct, true. That's nihilism. And we have to accept it.
