I believe that there are higher beings. It would be arrogant to assume we are the peak of ingenuity and intelligence. Pretty sure there is life out there somewhere, too many stars to not have at least one of them have living conditions (assuming that the living conditions we know of is the only way for life to exist). They could likely be far more advanced and superior then us.
God though? I'm agnostic with a bit of a twist. Most of my beliefs are rooted on epistemology so I'm a very big skeptic. I don't think anybody has the right to say a God does NOT exist, because we are mere mortals and no where close to omniscient level of knowledge, but I do question such a being's existence. I could say there would be beings that could very likely seem Godly compared to us, but I doubt it if we are discussing the classical theistic conception of God (an immortal all perfect, omnipotent, omniscient, omni-benevolent being who created the universe).
I don't like to rely on anything external for my sake. Religion is one of them. If somehow God's existence was proven false, I would not be affected. That way, I won't be broken or in denial like I can imagine millions of others would. If God exists and it is proven, well, I guess I have to bow down to the Almighty right. No biggie either way, if God exists, I'd like to ask the being a few questions and pay homage if required, if not, oh no, the world will continue to rotate and global warming will come eventually anyway.
Religion however, some people mentioned above, are people's interpretations for the unexplained. I think that is plausible, religion now are pretty heavily modified from what I've noted by human perspectives. I personally think that religion is just a safety net for people to hold on to so that they can sleep better at night. I'm not saying it is false, the truth is out there somewhere, so anything has a small chance of being correct, but it's not up to us to find out which one is based on our beliefs since we would be bias. I do admit that somethings are just too perfect, the way Christianity as a religion works is just remarkable. From an outside perspective, the way it functions seems like a mastermind created it, not just some human fanatic. However, that is what worries me, it is just... too perfect. It really toys with human flaws and works by playing those cards against us. Heh sorry if this doesn't make much sense, I didn't really write why.
Join me in Mikolism. It is a religion based off of perfection. Pinky and the Brain are two famous contenders, well, just the Brain. And I don't know wth I'm saying, I pulled two all nighters.
