Exactly what are you trying to pull here? The Bible is claimed by Christian scholars as not just some historical document but as the
Word of God.

As I have already mentioned before, Qur'an's existence in eternity is a disputed point not one of consensus, and even if there was unanimity over this, as I have
repeatedly pointed out to you, it still does not make the Qur'an a separate being, it is an attribute of God, and it has also been called as a reflection of God's knowledge.
Regarding the
trinity:
No, it is not easy "to think of a human as a trinity". Just what is the basis of this assumption? I never thought of a human in such a manner.
"...the mind is the conscious self..."
So, what happens when a person sleeps or becomes unconscious? So for a third of each day, a human is a
duality, or whatever term you want to use here? Is it the same for God too? Sometimes, He is a trinity and at other times He is a
duality?
"...the body is what we can see..."
So, when parts of a human's body get amputated, do parts of God also decrease in such a way? If parts of God can die, this conclusion is logical.
"... the spirit is the unconscious self that regulates heartbeat, body temperature, sugar levels etc."
Seriously? It is not the spirit that does these things, it is the brain (or the heart). If you can show me evidence of a human being whose brain or heart is unresponsive and still his "heartbeat, body temperature, sugar levels" are being regulated, then I will admit the possibility that it is the
spirit that is doing it.
What about the
soul which the christian doctrine believes will go to heaven or hell, does this mean that humans have four parts instead of three? Or by
spirit you meant
soul? In which case it would mean that the unconscious part of humans, which had no say in the matter of disbelieving in the divinity of Jesus gets to experience the torments of Hell.
No, this
trinity can not be applied to God, but for
animals on the other hand, I don't think it would be inaccurate to do so.
Animals also have a
conscious self, they are conscious of their surroundings, their hunger, even of themselves as was discovered by observing their reactions when they saw their own reflections. They also have bodies and "spirit" which "regulates [their] heartbeat, body temperature, sugar levels etc.".
