All of these ideas are held to be true by some. They cannot all be true. The bible reveals the truth about the nature of man. In the beginning God created the heavens and the earth. The very first verse of the bible tells us that God is the Creator of all things.
Life is a wonderful gift.
When life is gone, and we see the dead body, we know instinctively that nothing is left but 'dust'. It is not hard to understand why human imagination should have jumped to the conclusion that the life, which has fled, was the 'soul'. But animals too consist of 'dust' and the breath of life, and the same process happens to them when they die. Most theologians say no. It would be much too inconvenient to countenance such an idea anyway.
