What happened Yesterday touched on A Core Philosophy

After we left the mall yesterday, I found my car with a flat tire. Foolishly, I tried to drive it to a nearby gas station, but I ended up parked on the emergeny road waiting for a tow truck. My friend and I stumbled on to a conversation about "God." Now this is a very important topic that every human being has to tackle in their life. Their philosophy on "God" reflects greatly on who they are and what they do with their life. My belief is that there may be a higher being but I can't be sure on anything about this higher being. This school of philosophy is called "Agnostic." We also touched on wether there is a spiritual realm outside the mind, and if the mind is seperate from the physical. I've concluded in my thoughts in the past that everything, even our thoughts are physical. In philosophy this is called , "Materialism." The neurons firing in our brains created thoughts are physical and not "spiritual," or living outside the realm of my physical being. Atlast, after I stated these philosiphies of mine I confessed to him that I was afraid of Death, if my theory of me living in the last moment of my existence for infinity is not correct. See, Death is a scary prospect for me because I do not want to become non existing. But, if I do exist in that moment before I die forever (because before I die my perception of time discontinues, therefore creating infinity time and reality) than I will be ok with death.
