The idea is that it is easy from the perspective of Jewish law to slip into idolatry. One does not need to claim to be a creator of the universe. There is not on record any god that was a creator of the universe. The closest you get is Brahma but him himself was created from Brahaman, so he does not count . And Brahman is not a creator. he is the universe.
So to be an idol is not as hard as people think. And it is fairly easy for a person to become an idol. all he needs to do is to say one word "Evduni"{"serve me"} [Sanhedrin 61a]. To R Meir just by that one word alone he is considered "mesit umadiach" one to tries to convince someone else to serve an idol.
