Our perception of reality kinda sucks

The reality of human beings is based entirely on input from our five types of sensory organs. With our eyes we have the ability to experience a certain frequency range of light energy; our ears can perceive a range of vibrations traveling through the atmosphere; our nose can detect matter particles in the air to determine their origin; our tongue can evaluate a variety of substances to identify them before ingesting; and our skin detects physical contact with other objects. Each of our sensory organs has extreme limitations compared to possible stimulus.

Similarly, the only four dimensions that humans can experience are width, height, depth, and time. We know many other dimensions exist, we can prove them mathematically, but as humans, we are only able to experience those four as our entire reality.

Bottom line: we are only able to truly comprehend a VERY small fraction of our universe. We have instruments that can detect a far greater range of stimulus, but their range is not infinite, and they still must be translated into the small range that we are able to experience and understand. And they were created by four-dimensional beings, and hence they are bound to them as we are. For us to think that the provable universe ends with our limited abilities of perception is incredibly ignorant of us.

I believe there is other life in the universe – it may be few and far between, but the universe is certainly big enough to accommodate terrible odds. It's like if your odds winning the lottery were 1 in a million, and you bought 800 trillion tickets, you'd win more than a few times. What if there was life that existed well outside anything we have the capability of detecting? There could be a whole race of beings existing right along side of us, and neither us nor them would know the other is there. What if there was one kind of being that lived in every available dimension simultaneously, and therefore was aware of every kind of life that existed? That being could have considerable power by our standards, probably even appearing omnipotent. It might have the ability to create matter, manipulate energy, exist in all times at once.

What if this being is the one that we call God?  Sure the word “God” evokes images of a bearded man who lives in the clouds, and there’s a white pearly gate surrounding his land called “heaven” and all those lovely oft-sung metaphors of the Bible and the Renaissance. And I think the word has so much mythical stigma and emotional baggage. But all antiquity aside, what if this being were an actual form of life that existed in the universe, living in all dimensions at once, appearing omnipotent to us?  What if this being had the ability to manipulate matter at a molecular level, to create and control energy such as gravity, light, magnetism, and others we don’t even know exist yet. What if it had the power to govern solar systems, to move galaxies, to exist in all points of time and space at once.

Let's say hypothetically this being we've named God is managing our universe, maybe he governed the sciences that created our solar system and planet, perhaps he initiated the spark of life that created the first amoeba in the oceans billions of years ago, and that animal grew and developed into the complex life that currently occupies our planet. Perhaps he decides to pay the human race a visit – but there’s a problem. Our brains can only perceive a limited sensory input within four dimensions – so how would we ever understand exactly who we’re talking to if he just decided to show up? The only way to truly communicate with such a race would be to become one of them, to be born into the world as a human himself. So he selects a host female, impregnates himself into one of her eggs during her ovulation cycle, and is born into the world as a human being that can walk and talk among us. And as the human form of this omnipotent being, of course this guy would have great powers by our standards: manipulating matter, energy, even life.

This type of scenario would be perfectly acceptable in an Isaac Asimov novel or an episode of Star Trek. And yes those are science fiction, but they are earnestly based on real and theoretic scientific principles. But you put the word "God" on it and for many, the stigma tears it all apart. What if God was literally another form of life that existed in the universe, who just happened to be a hell of a lot more advanced and powerful than we are?
