Your theory is not as stable as you may think, my boy. However, it would be churlish of me to continue this debate of speculative theory on our present state in this world on the side that I do not truly believe to be the case. That being said, yours is one dependent on an unreliable basis: you feel as if you are alive, therefore you cannot be dead. This is a fool's deduction.

This is far from the truth, for you know not what it feels like to be dead. With that being said, your argument goes out the proverbial window, because you are making a theory based on only half an understanding of the proposed subject matter.

Too oft do mortals think death is the opposite of life, while understanding little of what defines either. In truth they are far more entwined and similar than you may think--and I admit that I speak from my own experience with both, but I have yet to see evidence that proves otherwise in this world.

After all, have you forgotten the ghost Pokémon in this world? They are indeed dead, yet they eat, feel, breed, and so forth.

What explanation have you for them?
