From ancient times, it is commonly believed that a living creature has an entity within, that keeps them alive, which has been referred to as the soul. It is also believed that upon death, the soul goes to heaven or hell. It is also believed in Christianity that the dead will rise again, and all human beings will be judged. The good may go to heaven and the evil to hell.
These ideological concepts actually started from ancient Egypt, when Osiris was said to have risen from the dead, when Isis supposedly put the torn pieces of his dead body together, he came alive again and entered the underworld. A similar story is told in Christianity, that Jesus rose from the dead and went to heaven. From these two classic examples, the Egyptians, who were the forerunners of most of our believe systems today planted the concept of life after death, and further expanded upon during the Christian era.
To get to the bottom line of this question, ask yourself: Whether ants, frogs, birds, lizards, dogs, butterflies, insects, the hen that we eat often, and fish in the sea. Do you think they have souls, since they live and die just like human beings. Most people will say ants do not have souls, but a human being will not want to say do not have a soul.
Both the ants, fish, worms, human beings and living creatures have a life form called CONSCIOUSNESS, integrated into their bodies which allows them to see, hear, touch, taste, and feel. It is consciousness that allows living creatures to experience life through their five senses.
What is the source of this consciousness, one may ask? The consciousness of a man has its origin in a SINGLE SPERM, among the many sperms a man ejaculates. The consciousness of a woman has their origin in TWO SPERMS, among the many that are released into the womb of a woman every 21 days; that is those women that have not reached menopause.
Each time a man have intercourse with a woman, there is ONE SPERM, within the many that is ALIVE, and is the root of consciousness that travels its way into the womb of a woman seeking one of the female sperms that also has consciousness. As previously mentioned, only two sperms within the female have consciousness, which are released into the female once every 21 days and stays alive for 5 days in the womb. If those two female sperms are not fertilized within those 5 days by a male sperm with consciousness they die and come out in the female menstrual period as blood.
When a male sperm that has consciousness fuses with a female sperm that has consciousness, a fetus is formed, and it is this new united consciousness that then forms a new fetus in the womb of the woman. In consciousness is also an intelligence, and these two together fused with a body become a living child that is born into the world as human being. Hence the life source of a creature are from the sperms of their parents.
Hence a human being and living creatures do not have a soul as a separate body or entity that lives after death, but the living body is consciousness that is wearing a body. Upon death, both the consciousness within the body ceases to exist, the same way sperms die when they are exposed outside for a short while.
It is rather the angels that have a separate body within themselves that is immortal, which is the true angelic body of the angel. The person that was Osiris, was an Elohim in the body of a human being, hence he had an angelic type body within his body, which was already immortal.
A human being has three bodies integrated into one, : INTELLIGENCE, CONSCIOUSNESS, PHYSICAL BODY. An angel has four bodies: INTELLIGENCE, CONSCIOUSNESS, INNER BODY, OUTER BODY, three are integrated as one, and the fourth which is the actual angelic body can exist separately. Osiris, was the same person that was Vishnu, Shiva, Rama, Elijah, Moses and many of the lives of the major prophets. In all those cases he had an inner angelic type body, which if the physical body where to die, can be covered again with another physical body by a spirit, hence it will appear the person resurrected from the dead.
Only a person with an angelic type body can appear to resurrect from the dead, because their inner body (fourth body) is always immortal, but a normal human being dies the same way that other living creatures die. When a human being is created as an angel, they become immortal and continue to live as angels, even though the physical body dies. So all those that have been created as angelic duplicates in heaven will continue to live forever, even though their earth counterparts may die in the flesh here on earth. Their angelic counterparts do come back to earth, and walk around in the exact same bodies like their earth counterparts. Only a person with an angelic type body can go to heaven; angels are created by a spirit of God from a living a human being, not dead human beings. So one has to enter heaven as an angel before death, not after death. Excerpt a man is born again by the spirit, (created as an angel), they cannot enter heaven.
