We have the natural question about how and why we exist. However, if a superior being exist (hypothesis), I don't think that we must pray Him, because that being has never revealed His identity until now. In the past dishonest religious leaders emerged by inventing legalistic policies that supposedly came from "God". For instance, the jewish priests invented that a god called YHWH liked to receive the blood of sacrificed animals and demanded his people to abstain from swine. We now know that these are human inventions. So, we were forced to believe that we must worship a non-existent being created in the mind of scribes.
