heflores,
- Death is a result of life,
No this is incorrect. Death is the result when life fails.
death can not happen if life didn't happen.
True, but death cannot begin until life ends.
One can not die if one did not live.
Agreed. This is a necessary dependency.
Only to the extent that the dying process of anything living tends to be a short transition rather than an instantaneous on/off switch. When a person "dies" their neural networks remain intact to some extent depending on environmental temperature and related conditions. The final disintegration of such networks occurs over time (minutes) through a lack of nourishment and other supporting infrastructures, i.e. the hormonal systems.
and are subset of one another:
Death is not a subset of life; death is strictly the result of a transition from one state (life) to a fundamentally different state (death).
-Our skin is constantly dying and replacing.
-Our body cells are constantly dying and replacing, while we are
still alive.
Yes but each of these structures are separate entities. A cell can be alive or dead, it cannot be both. The appropriate comparison with people is that when you die you are replaced by your son or daughter. The replacement process of cells is a generational process.
In a similar manner we could extend the analogy to the human race. Individual people die and are replaced, but the human race continues to be alive. Only when the last person dies can we say the human race is dead. Many species have already experienced extinction in this manner. All the time there is at least one human then the human race will be considered alive. The fact that individuals are replaced have no bearing on the question of whether the human race is alive or dead.
At no time can something be alive and dead concurrently.
- What may be perceived as a dead seed, gives life, so life must be contained within death.
As you state, a seed can be perceived as dead. But that is a false perception, since the seed is not dead. A false perception such as this further supports my argument that at no time can life and death coexist or be a subset of one another. They are distinct and separate, with only a transition from one to the other in a single direction.
However, the seed analogy is interesting because seeds are often not considered alive either. A seed is a package containing most of the components needed to create new life; it could be considered potential life or dormant life but lacks some key catalysts. When the seed casing is penetrated and the final components are added, i.e. oxygen, water, heat, and light, then the seed begins a new life. However, if seeds are not properly protected then they can rot and effectively lose their potential to start life, and at that time the seed could be considered dead and incapable of returning to life or starting life.
Please note that cause and effect implies a very strong subsety of one another,
No it doesn't. In fact quite the reverse is equally if not more likely. Several years ago the rate of death in Europe due to colder than usual weather was caused by warmer than usual currents in the Pacific Ocean. How can one be a subset of the other?
Something can't cause another without being related to it.
Incorrect. See my example above. However, we can conclude that a relationship is formed because of the resultant effect. But this opens up another vast debate concerning the philosophy of determinism, and I am quite sure you don't want to explore that just yet.
