Physicists got it wrong. Atoms, electrons, quarks - all that stuff is basically sound, but the theory goes further. Much further. In actual fact, the most fundamental particle in our universe is...the basketball (or 'b-ball'). Every material on earth is, at the initial level, constructed from b-balls. Carbon is b-balls. The blood flowing through our b-ball veins is made of b-balls.
Actually, a passing knowledge of RPGs (especially of the melodramatic Japanese variety) will help too - but mostly the b-ball thing. Focus on the b-balls. You may still be a little confused and wondering if this BSUJG business is really worth your time. Don't worry: it is.
