Skill is worthless without practice, as well as practice without skill.

I have no means of knowing if Gods exist. Both the obscurity of the question and the shortness of human life are obstacles that impede knowledge.
Protagoras was a pre-Socratic Greek philosopher and rhetorical theorist. According to Plato, he is one of the sophists. Plato credits him with inventing the role of the professional sophist. He created a major controversy during ancient times by implying that there is no objective truth. Whatever one deems to be the truth is true. Individual relativity was atypical for the time, contrasting with both popular opinion and other philosophical doctrines that reality and its truth must have an objective grounding.
