Lets be philosophers

It's only human nature to ask so many questions. I've been told off in class, for asking questions, pondering about them... And yes talking to myself since no one else has bothered to answer my questions. (The school supervisor has reccomended a psychiatrist for me... LOL...)
Anyways, back to the topic... Does time exist? Is there actually a past, present and future? Or is it just an eternal now?
Is everything made of the same thing? As in, in physics and chemistry we are taught that an atom is made up of Protons, Neutrons and Electrons. And the number of proton decides what element this atom is. Could it be just that these protons, neutrons and electrons are actually small particles of (un)charged 'matter' [since neutrons are neutral in charge].
