You Are Not the Body, So who are you? Options

There are many people who believe that they, real selves, are in fact their body. However, there have been other people that have suggested that you are actually not your body, but an eternal soul.

An analogy supporting this would be that we are to our bodies as people are to cars. A person drives a car, has to take care of the car, can decorate the car, but is in fact not the car itself.

Sound too supernatural to be for real? Discuss.

For the sake of this topic, I'm going to switch sides and provide a counter-argument.

There is no proof against my idea that our perspective may be nonexistant. Our personalities and thoughts may just be a complex system of neurons, an intangible algorithm from within our body. We have no proof that we are really sensing our environment through the spirit with the body as the window. Yet we believe it, because we cannot understand something we know to be true being wrong.

I say that if we are able to believe that we are spirits and souls, which we, being human, cannot fully understand, why can't the other extreme be possible? It is just as likely that we do not exist as spirits, but only as flesh. Neither of them have solid proof, so each are just as likely to be the case.

Besides, its not such a far-fetched idea. We may not understand how vast the algorithm of thought and perspective is, but we also do not understand how vast the universe is. We do not understand how vast God is. We do not understand much of anything. Does that mean its impossible?

I am somewhat arguing both sides. However, what I'd like to accomplish with this is to put them on an even plane. We will never truly know which is right, we can only guess. However, with this, I'd like the guesses to be even.

Also, religion is not solid proof. Please do not bring religion into this. Spirituality and religion are not the same thing. You may talk about souls if you wish, but please do not cite religious texts, as not all will accept them as proof. I honestly do not want to start debating about religion in this, as its a pretty interesting topic.

Also, as a request, can someone jump sides with me?

What proof is there for it?
