The inventor doesn’t take part in any religion and doesn’t believe in any higher entities. Apparently he hasn’t outright called himself an atheist, but it seems to be the case. When asked whether he believed "there was some kind of destiny involved" in humanity's transition to a multi-planetary species, rather than "just physics", Musk responded:

Well, I do. Do I think that there's some sort of master intelligence architecting all of this stuff? I think probably not because then you have to say: "Where does the master intelligence come from?" So it sort of begs the question. So I think really you can explain this with the fundamental laws of physics. You know it's complex phenomenon from simple elements.

Musk has stated that he does not pray, or worship any being, although previously admitted to praying before an important Falcon 1 launch, asking "any entities that were listening" to "bless the launch". He is a firm believer that religion and science cannot co-exist.
