This has certainly been an interesting debate regarding the soul.
Are there aspects of the mind that owe nothing to the physical functioning of the brain?
Are there aspects of the mind that do not correspond to any physical area of the brain?
What exactly does the soul do that confers consciousness on us, and is this influence transmitted to the brain?
Does an immaterial soul interact with a brain and body of matter? Does the soul control the body at all?
If so, how exactly does it do this? What force or causal influence does it exert, and by what mechanism? By what mechanism can an immaterial soul possibly alter the state of the body or affect the brain?
Why would God create an immutable/unchangeable soul-nature and then make it subject to the changeable and imperfect nature of a fallible material body, and judge it for the actions committed by that body?
Why do we even need such bodies, if at best they can only allow the true nature of the soul to shine through unaltered, and at worst obscure it?
What is God’s rationale for imprisoning souls in bodies and holding the souls responsible for the uncontrollable irrationalities of those bodies?
Where is the soul hiding?
"The soul is spiritual or metaphysical it can't be detected by scientific method."
To say something is “spiritual” or “immaterial” does not explain what it is, but only what it is not; all it means is that an immaterial object neither feels nor exerts any of the forces that act on matter.
In my opinion, in invoking "spiritual" or "metaphysical", we know no more than when we started; we have not answered the question, merely moved it beyond the realm of the answerable. This only muddies the waters, adding additional levels of complexity and mystery without actually explaining anything.
"There are animal brains much more sophisticated than humans and they don't produce consciousness."
Which animals are these?
