Why Are There Galaxies?

They make space clumpy. They seem to have been created and shaped a
long time ago. They could be a big argument against a "single" big
bang. Stars come out of clouds,and that means these was not one big
cloud. If blackholes are at the core of galaxies they must have
developed there first. Why do astronomers tell us stars are forming
in the outer fringe of the galaxies? What makes that the rule in this
spacetime? Seems star making has slowed down by a million % Never
heard of a new galaxy forming. Well this is another mystery. The
forming of galaxies. Bert

Apparently ('cos I wasn't there) the Big Bang wasn't completely unifom so
eventually matter clumped together in places.
That's not a particularly scientific answer, but I think it's more or less
the case. :-)
