If he does, then he is. Everyone has a different idea of him and there's no 'facts' I know of that you can build an opinion close to the truth upon. But if he doesn't then technically no, he can't be obscure as he's not real. In the sense that a fictional character can only be obscure in our minds. But objectively is just an idea held by people and therefore open to interpretation and malleable. Baring in mind the obvious "you can not prove he is or isn't, but the burden of proof is on the extraordinary claim", if you regard the idea of God as the leap in the first place.
How can the nature of god be known by all or most of us when we all contradict each other with our opinions on the matter? Every person has a different opinion about what god stands for what he has done and they cant even agree on f ing name of god. Clearly god is obscure. He hasnt been discovered by the living. Just because your leaders (who lie all the time mind you) gave you a book that tells you about god and that he exists does not mean you have discovered god. Thousands of religions thought the same thing but they must all be false if yours is right and yours must be false if any of them are right. Maybe the one true religion hasnt came yet. And id argue that it hasnt since no religion makes all other religions look like the work of children because its so profound. They all make themselves look like they come from children all on their own! Grow the f up and stop believing in fairytales you grown children.
So he can't be obscure. Oh, wait, I need to put 50 words down here to post my opinion? That's dumb, because the best arguments are brief. As Polonius said, Brevity is the soul of wit. I shouldn't have to put a long paragraph nobody wants to read down here.
God can not be obscure if he does not exist. He is simply something created by man to explain something that we can not understand. Thus different religions exist because people will believe whatever will make them happy. There is little to no proof of his existence and someone could very easily attribute the air we breath to his existence. If he does not exist then he can not be obscure, thank you.
I believe he is real, but that is my stated opinion. Therefore this topic is not exactly an argument since we all have our opinionated viewpoints. But, I do believe that he is real consider that there is much proof on the topic. There is also much proof on the topic that he is inexistent. Technically this is all opinionated on our religions.
