If we were simply the brain we would have no need for consciousness as we would simply be robots programmed to react to things.
Isn't this what you are doing, though? Things happen, and you react to them, based on your best assessment of the situation. And if you don't have any assessment of a situation, you just pick a random choice, hope it's good, and go with it. At least that's how I do it. How do you do it?
This is not the case, we are live beings, we are consciousness, we have free will, we're not the brain. If you have ever had an outer body experience, you would realize this.
Free will just means we have a choice on how we react to our surroundings. That's all. It doesn't matter if you're practicing free will within your body, or outside of your body. You're still experiencing something, and racting to things. Unless you don't react to things? Or maybe you react to things not based on your best assessment of the situation (aka based on what you have learned in the past), but instead react based on some outside source of information that comes from outside of this world? (that would explain why you have made so many awful choices...)
Tell me, how does the brain create a consciousness? Because from my understanding it can neither be created or destroyed.
Energy and matter can neither be created nor destroyed. Let's consider your side of this. If you have a thought, you have taken one state of how things are, and changed it into another state, whether that's changes in electrochemistry, changes in cosmic consciousness, changes in some ether, or whatever. Doesn't matter. Change, of any kind, requires some amount of energy. Again, doesn't it doesn't matter what the energy is, or where it comes from, just that it requires energy. Pretty much by definition, since nothing can move or readjust without using up some energy. You claim that consciousness can not be destroyed, but that would suggest that it would have to go on thinking about things and changing from one state to another indefinitely, using up energy in the process. That means it would have to use up an infinite amount of energy. But the two things we absolutely know for a fact are 1) energy in our universe is not infinite (entropy will eventually cause all energy in the universe to collapse to zero), and 2) you can't make a perpetual motion device that creates energy out of nothing. Having a consciousness that can never be destroyed, and is thus always using up energy to think, is basically the same thing as having a perpetual motion device that is creating energy, which, as you have also said, can not be created or destroyed.
So, the answer is, consciousness is created by taking some energy source (food, water, electricity, cosmic carma, whatever), and converting it into changes of the state of mind. Biologists, psychologists, and scientists in general would say that the body converts food and water into electrochemical components, sends them to your brain via your veins and arteries, and your brain then uses that energy to run and process things, changing your perception, states of mind, and thoughts, which gives you consciousness. And if your brain ever runs out of energy (you die, or are brain starved from choking), your brain can't convert energy into consciousness any more, and your brain simply shuts off, like your computer would if you were to pull the plug.
People who are not biologists, psychologists, or scientists, say other things.
