Charge did not appear out of nothing in the sense it is not balanced ie
there in no net charge - which means there is an equal amount for positive
charge to negative charge. So you question is why does charge exist? Well
in science some things are accepted and charge may in fact be one of those
things - but strangely there is a more fundamental reason at work - namely
local QM gauge invariance - see
