What if life is just an Illusion?

The logical conclusion is that we are indeed living in an artificial reality. Take the smallest microbe on the planet, it knows from birth that it needs to eat, rest, and survive. How does it know this? Nothing teaches it, it cannot see, it has senses, but it has no awareness. We as humans are born, and we know that our eyes are for looking, fingers for touching and exploring, we have senses. We know how to use them all, nothing has taught us this, it is simply ‘there’. We have emotions, we can relate to each other? We cannot communicate with anything except our own species, we can only attempt to do so using common denominators such as affection and co-operation.
Each species has a brain of varying size, some the size of a pinhead, and yet every species knows how to survive, and reproduce.
This alone should prompt anyone to question our existence. The brain works on electrical impulses, we assume that these are generated within.
Take a step back and consider that the brain is affected by all sorts of frequencies, and the damage that can be done by some of them. If there are malevolent frequencies then are there benevolent ones? If there are, then conclusion is that the brain is not a self perpetuating thought generator, it is a receptor and is controlled from birth by an external transmitter.
The world appears to be a strange place, where events occur, almost by some sort of communal provocation. There is no reason for some events to take place but they do, every day.
Maybe science and religion both have something in common, maybe they will never find answers because there aren’t any. If their thought processes are controlled, they are simply part of a plan to see what happens ‘if’, and how different thought processes interact between different human groups.
If this much is true, then we are nothing more than an experiment, a living, organic set of pieces on a very complex chess board.
