We die because over time the materials that our bodies are composed of start to wear out and break down. Eventually the rate of wear and tear surpasses our ability to grow and renew, and we die. Or something along those lines, anyway. :)
We're not perfect beings; we are mortal beings, and part of that mortality is death--it's built in to the equation of every living being on the planet, be they human, canine, feline, vegetable, animal, fungus, bacterium, they are, every one of them, fated to die. And, to be frank, that's a very good thing, or the planet would be so deep in beings there would be nowhere to live for any of them. I'm 67 years old, and to be even more frank, I'm not afraid of death. Some nights, when I'm in a lot of pain (from arthritis and other things), it can even be kind of a pleasant idea. But, I sense you're quite a bit younger than I, so the idea of death is probably not one you face with equanimity. Give it time, kiddo.
If we live forever, the world may overpopulate. Plus, it's the circle of life. One day your heart will stop beating. Currently right now, there are at least 100 people dying. Every second of your life, somebody dies in this world. But another person is born. It's the circle of life, and our population will be balanced. That's how God created us. :)
We die because if we never died then we would have way to many people on earth and then we could never have any kids... This may seem like crud and not truthful but we were born to be born have babies and die.
We die because if we did not die we would die, paradoxical, but true. Living things have a metabolism. Simply, we need food. Living things grow. We need molecules to create other molecules. Ultimately, we are food for something. To be eaten, we must eventually die. When we die we are decomposed by the decomposers. Decomposers change our molecules into other molecules, fertilizing the soil. Plants use these nutrients to grow. We eat plants, things that eat plants, things that eat things that eat plants, etc. Plants also convert CO2, light and H2O into O2 and C6H12O6. We need O2 to breathe. So you see, if we did not die we could not live. This is simplified so anyone who is going to say, "Well, then couldn't..." or "That doesn't explain...." look it up. This is just the surface of a concept.

Every living thing has a purpose,plants/cells/insects/animals/humans.All living things die.Then even after death some things still have one last purpose to feed the still living/or hold the earth together becoming soil/fuel to burn.The list is long.So we die when our purpose on this earth is over.Im a lady of faith so I believe I will die when God's purpose for my life is done on this earth.< Everyone has there own believe on this:)
One fact for sure. Everything has a beginning. Everything has a ending. On this earth. Yet nothing leaves this earth.
