Read this Keith,as you sound so sure with your opinion,apologies if I'm reading you wrong.

          " "the Universe was composed of radiation and subatomic particles. What happened next is up for debate - did small particles slowly team up and gradually form stars, star clusters, and eventually galaxies? Or did the Universe first organize as immense clumps of matter that later subdivided into galaxies? " "
    As DMcG stated above we need to define Galaxy.
