For an essay.
1. A ghost is not alive. "Life" is dependent on a physical body. If the physical body is dead, then there is no more "life" in that body. 2. A spirit cannot function the same as a live, physical human person. Many people believe that spirits or the intelligent collective of a person, is really much like a computer program and saved data and gets plugged back into the matrix to exist in a virtual existence instead of a physical existence. 3. Some people believe that after you die, your spirit gets recycled into a new body and a new physical life to start over. So look into Zen Buddhism and research reincarnation for your essay and good luck to you.
I can't speak for anyone else, but for myself, I don't believe in life after death because there doesn't seem to be any evidence for it. For that to occur, there would have to be some kind of entity that is separate from the body (i.e. the "soul") but nobody has ever been able to prove that this exists. Also, the fact that people from all over the world have widely varying concepts of what happens after death suggests that the basis for this belief is rooted in culture, not fact. In many cases, I think that peoples' natural fear of the unknown has simply been exploited to maintain wealth and power for religious leaders.
By definition, death is the end of life. Anyone who wants to argue otherwise has a pretty tough argument to make.
While we don't 100% understand the human brain, we do know enough to say that that's where consciousness happens. Drugs (including hormones), tumors, and physical damage to the brain affect the person's personality. Monitoring the amount of electrical activity in a brain can tell the difference between someone awake, in deep sleep, or dreaming.
In the Middle Ages it may have made sense to think of consciousness as a fifth element, not reducible into smaller elements. But now that we do know what a brain is made of, it's clear that consciousness requires an extremely complicated physical structure.
Stories of "ghosts" were invented as then-simple-seeming explanations for mysterious phenomena. A lot of those phenomena have since been explained (if you're ever dared to stay in a haunted house, bring a carbon monoxide detector).
The condition of the dead is made clear at Ecclesiastes 9:5, 10, where we read: “The dead know nothing . . . There is no pursuit, no plan, no knowledge or intelligence, within the grave.” (Moffatt) Death, therefore, is a state of nonexistence. The psalmist wrote that when a person dies, “he goes back to his ground; in that day his thoughts do perish.” (Psalm 146:4) The dead are unconscious, inactive.
When pronouncing sentence upon Adam, God stated: “Dust you are and to dust you will return.” (Genesis 3:19) Before God formed him from the dust of the ground and gave him life, Adam did not exist. When he died, he returned to that state. His punishment was death—not a transfer to another realm. What, then, happened to his soul? Since in the Bible the word “soul” often simply refers to a person, when we say that Adam died, we are saying that the soul named Adam died. This might sound unusual to a person who believes in the immortality of the soul. However, the Bible states: “The soul that is sinning—it itself will die.” (Ezekiel 18:4) Leviticus 21:1 speaks of “a deceased soul” (a “corpse,” The Jerusalem Bible). And Nazirites were told not to come near “any dead soul” (“a dead body,” Lamsa).—Numbers 6:6.

That's like saying road traffic accidents only happen to older people.
The bigger question is why would anyone believe in life after death? There is no logical reason why such a thing would be actually possible.
One very compelling reason is that we have no solid evidence for life after death. We have a few stories about near-death experiences, but nothing that we can rely upon.
This is an aspect of existence that we are in no position to understand. Perhaps we live the same life repeatedly, and have no idea that this is the hundred millionth time... we see time as a linear thing that cannot go backwards, but what if that was not true in another reality? What if our lives are permanent markings on a tape that can be replayed at any "time"....
Of course, that's all completely speculative... and of course it wouldn't be very helpful for someone who died of bottulism at age 3...
they is no evidence for a soul. The idea of a soul came from people long ago, well before modern science.
if there was life after death it wouldn't really be death.
My main reason is that there is no evidence of any kind -- plus, it wouldn't make sense. Your body IS you. When it stops, you are DEAD. Gone. Like wherever your lap goes when you stand up.
