The brain is always sending electrical signals. One signal leads to the next leads to the next. When the electricity stops, you are dead.

I'll give you an example. (Extremely simplified)
You see a dirty dish on the table. The light reflecting off of the dish goes into your eye. Your eye's lens focuses it on the retina, the retina absorbs the light and sends an electrical signal to the occipital lobe. The occipital lobe processes the signal and sends the processed information into the frontal lobe, parietal lobe and so on. It is within one of those lobes that the signal connects with a memory about what dirty dishes look like, your dishwasher, and that you need put dishes in it to make them clean, and other types of logic-based memory like what things you need to do to keep the house clean and why you should clean it, etc. Those signals are then sent back to through some more logic processes and finally back to the cerebellum and thalamus and a few others which controls motor functions which sends signals down to your muscles that allow you to pick up the dish and put it into the dishwasher.

TL;DR the electrical signals are not just created out of thin air, they are a continuous chain reaction based on internal and external stimuli that began with the beginning of your life. Or I suppose you could argue, the universe.

You did this to me.

I can just smell the macbook pros, scarves, and lens less thick black rimmed glasses on half of these "deep and philosophical" paragraphs below me.

the brain is self-perpetuating. Its existence is the existence of consciousness. It like asking why a rock is grey. The rock is grey because that's simply the way that light reflects off its surface. It is grey because it exists that way.

If you want to ask how consciousness comes to existence, well there is no good answer for that. To understand that, we need to understand everything about ourselves - which we don't. Some theorists aren't even sure whether our brain has the ability to comprehend itself in its entirety.

What I pictured.

OP, you made me think. :(

the primary response is given by our senses and the information should be then processed by the brain. (so the initial signal is pretty much one of the senses(and like binary more and more simple digits can make more complex numbers))

The answer is genetics. The instructions came from our ancestors.

Here comes the smart, philosophical, and deep people, prepare yourselves for paragraphs

there is no free will. only the illusion of free will. we are all simply extremely complicated machines which are preprogrammed to follow a certain path due to previous actions. imagine if you could know the motion of every atom and know how it all works. you would be able to predict exactly what is going to happen. Thus no free will. But what about quantum mechanics? Well that doesn't help us either. It simply introduces and element of randomness into the equation not choice. However since no-one can know all of reality then we have to pretend that free will exists and it is this pretence that allows morality back into the world.

when you think about it though, we're all just brains protected by suits made of muscles, skin, bones, etc.

Actually OP the body does not send out electrical impulses for movement. The nerves send out an "action potential" which basically causes Sodium Ions and Potassium ions to switch places through a gate, causing an impulse. There is an electrical because of this, which is why it is commonly associated with electric impulses.

I see all of the explanations below me and they are all in fact smart and some accurate. Although OP would continuously ask the child's "What happened before that.. and before that... etc.," question, it will eventually lead to a version of the chicken and the egg scenario.
