Is there a part of philosophy that deals with this?

[Jeppe F]

Is there a part of philosophy that concerns questions like: "Why are we here?", "What happens when you die?" and "Is there a reason for our existence?"

I'm asking 'cause these thing intrest me alot.

Luke says metaphysics, and he isn't wrong. "Ontology" goes a step beyond that. You must understand metaphysics in order to understand "ontology," the specialization of those questions.
Another specialization of the questions is called "cosmology." There are 2 kinds of cosmology: physics, and metaphysics. the cosmologists of physics HATE us who are metaphysicans! And because they are "elites", we are able to criticize them not for being elite but for failing to see the bigger picture. They see only the physics. Metaphysicians see what Curtis Edward Clark calls being in the "cosmic wheel" and looking for the "single intelligible object" mentioned in the Syntopicon.
Being in the cosmic wheel makes you find answers to "Why am I here and why is the universe here?"
Marcus Aurelius, the Stoic Roman Emperor, told us to discover those things, or we would not ever know who we were, nor know our place inside that "single intelligible object." Aurelius called that object "the world."
Cosmology of metaphysics can further be broken down into theological cosmology. There is a book called "Cosmology in the Sacred Christian Tradition."

Find the Syntopicon in your library, and read it. It's cool reading material.

There are some philosophies that attempt to address those questions. Look up "existentialism."

Religions are much more concerned with those questions, and their answers are at least as useful as the philosophers come up with.

Buddhism has a very clear idea of those issues, with samsara, reincarnation, and nirvana as parts of their model.

Most English speakers are familiar with the Christian model of heaven and hell and God's will, possibly with the idea of a purgatory, but I'm guessing that hasn't satisfied you yet.

I chose Taoism partly for its answers to those questions. They don't have a very elaborate model, and it may be quite disappointing after hearing the promises of some other systems, but it comes closest to an empirical/scientific view.

You may want to investigate science as well. Certainly biology has turned up some surprising evidence (see extremophiles, for example). Astronomy and astrophysics have discovered a lot about how the universe has and is evolving. Genetics have revealed a lot about how our DNA works. Medicine has discovered quite a lot about what happens to bodies when we die.

And then there are also quite a few mystics who talk about those questions. You might want to investigate remote viewing, spirit mediums, trance channels.

you should read a book by mary m. bauer titled the truth about you : things we don't know we know, but honestly i don't think you should worry that much about your existence when you're just 15. enjoy your teenage years. trust me after all the knowledge you'll gain. you'll still be searching for answers. i wish you well.

Look up "Metaphysics". Depending on the metaphysics of the philosopher you choose, those answers are addressed. Ontology is a main category of metaphysics and deals with reality and existence.
