Or alternately, words do not adequately describe Scientific concepts, The language is not precise enough, this is, and has been, an ongoing problem since the beginning of science, words in Science as opposed to words as everyday communication, have a PRECISE meaning i.e. Green as a word means anywhere between Blue and Yellow as a Science concept it means a precise range of wavelengths of light between 50*10^-8 and 57*10^-8m . Therefore The Big Bang is a very fuzzy "word" description of what Scientists Theorize happend at the very beginning of the Universe,(the moment of Creation for any of our closet Creationists out there, The second after "Let there be light") any the models they use are all mathematical.
