That is true. But then your very example indicates that it is a machine working on oxygen as fuel and that is far from being the original source of awareness.

It is okay. I do not expect you to contemplate and intuit diverse variety of consciousnesses that surround our bodies. The intuition will come someday automatically. The following is for the benefit of those who have allowed their minds to be flexible.
You think the shadow is the substance:
so to you the substance has become a cheap toy.
Wait until the day when that substance
freely unfolds its wings.
Then you will see the mountains become as soft as wool,
and this earth of heat and ice become as nothing;
you will see neither the sky nor the stars,
nor any existence but God - the One, the Living, the Loving.
~ Rumi
Some will say that what Rumi says is poetic BS. But some mighthave experienced this. The ego sense in man constraints the intelligence in such a manner that it believes that intelligence is localised in man's brain only. And when a man dies his intelligence, memory etc. vanish. Such ego-full men cannot even comprehend that an emergent intelligence cannot have power to determine truth of a proposition, since the intelligence in such case is arisen out of determined processes. The outcome of such thinking is futility. A chance birth due to sexual activity of parents, a life full of toil, and then an inevitable death. Those who propound such machine like origin of intelligence however keep fighting with others claiming that they know better than others. How? When the awareness is emergent from deterministic process, what is an individual? And how can his opinion be objective? But such is the nature of ego .. It will not pause to contemplate.
How different people are born with different qualities? How a new born joey, still blind, can find nipple of mother kangaroo all by itself? It is not that only humans are intelligent. Many forms of intelligence-awareness surround us, in form of variety of animals and plants ... and also as inert substances. But we have erroneously come to believe that intelligence arises in discrete inert bodies.
Consciousness surrounds us. We cannot see the tranquil ocean of consciousness. In it we mistake the reactions-experiences that arise temporally as the consciousness. We mistakenly label the experience as the consciousness. Our bodies and all other bodies are instruments of experiencing the all surrounding tranquil consciousness in millions of ways. A disappearance of a local centre of experiencing (so called death) means nothing but transformation. Objects come and go but the mind and the senses are eternal.
Our body and its apparent intelligence is like a window that seems to be the originator of sunshine to the one who has never seen the sun.
As long as we imagine ourselves to be the localised body-mind complex, we are tied to the chain of determinism. Regarding this the Buddha said:
"There is, O monks, an unborn, unoriginated, uncreated, unformed. Were there not, O monks, this unborn, unoriginated, uncreated, unformed, there would be no escape from the world of the born, originated, created, formed. Since, O monks, there is an unborn, unoriginated, uncreated and unformed, therefore is there an escape from the born, originated, created, formed."
If the consciousness in us was not unborn then we would always be bound to the chain of determinism originating from the inert mechanism that (supposedly) engendered the consciousness.
