Most people says it’s made of atoms. In reality it’s made of more for example the atoms are made of Neutrons, Protons, and Electrons. 
The Protons are made up of Quarks two up and one down Quark. Neutrons are made up two down Quarks and one up Quark.
The Quarks are made of nothing and alongside the Quark is the Gluon also made of nothing. Does this mean the world is made of nothing are Quarks and Gluons made of something so small we still can’t see we don’t exactly know we just have to wait and see what happens.
If you were fully immortal you wouldn’t die from that you would be floating around in space forever alone. On the other hand, you can watch humans evolve and take control of the galaxy.
You would do everything and become the board of everything you can do. You would see black holes destroy us all and watch the end of the universe after seeing everything. Even after that end, you would still be alive others would to if you were tested on by the government if you were found out. Many bad things can and will happen if you become immortal so what we thought was good was actually bad and there are many more bad things we think are good.
signals to the brain.” It then states Plato’s dark cave story “You are stuck in a dark cave and you see shadows of people on the walls are the shadows real peoples shadow so you walk out to look for them but he found nothing.” This represents that are brain are not perfect and we are flawed. Because of this your brain could be sending the wrong signals to your brain so what I’m using to type this and what your using to read this could be wood or even a rock and rocks could be water and water could be metal 
we don’t exactly know. The only we we really know that some stuff is what we think is because we can see the effect things have on them. My question is if water was metal and they boil water at 212 
fahrenheit then what if metal actually boils at 212 fahrenheit and we just needed a ascues for reality or if we got the data wrong because we are flawed or the world is as it seems we just have to believe in what we believe I am so this is nihilistic and all I have to say is believe in your own religious practices 
but if you don’t know what to believe and want to know the definitive answer then you are probably agnostic like me but if you are Agnostic then you have to know one thing we will probably never know the answers to some questions but me question to you is do you believe that are world is what it truly is or not and what religion do you practices because a true world is different a Christon’s true world God is real but a Atheist’s true world God is a lie but to a Agnostic person like me then you believe we just truly don’t know or if you a Nihilist then you don’t believe in anything you reject religion.
