What is the nature of the soul? Is it akin to a personality? Does the soul remain unchanged throughout a person’s life even though a person may change as it grows?
There is a lot of excellent information out there so I am assuming you are asking random people on the Internet because you are not truly interested in knowing the answer.
However, your questions do offer me an excuse for spouting off on the matter:
So here I am at the monitor, participating within a continuous physical reality,
the experience of which is formed by events such as the release of photons from the screen,
travelling through space to the retina causing chemical reactions,
followed by a cascade of events that include the travelling of action potentials down axons,
releasing neurochemicals across synapses where dentrites meet.
These “messages” travel through the midbrain to the occipital cortex and across areas of the brain involved in “decoding” the “information”.
All that is happening according to the model of neural physiology, are complex biochemical changes - no “mesages”, no “information” - just chemicals.
But because of all this, we are able to understand what is on the page.
That these words have actual meaning is possible because we also belong to the realm of mind and spirit.
One knows, understands.
So how does one come to know the knower. One can seek oneself in the realm of ideas, and revealed truth. One can also sit in silence, in prayer, leaving behind illusions: misunderstood, misapplied and/or mistaken teachings - in that silence, beyond attachments, realizing oneself.
Ultimately, one is led to He, in whose image we were created - God, the Source of all Being, Beauty, Goodness and Truth.
BTW: this physical, mental and spiritual stuff: all are aspects of the unity, the whole that is the human person.
It is pretty clear that if one does not have an inkling of the divine, of the world of the spirit, one will end up talking about hominids and such, missing the whole point.
