Do Blackholes Form Galaxies ???

Blackhole was there first and draws all the material(star making
material) towards it,and stars are formed,and over time you have a
galaxy. A blackhole can't be at the center of a galaxy any other way. We
read that the Milky Ways blackhole has a mass of 2.6 million suns. In
galaxy NGC the Hubble has made a picture of a massive blackhole,and the
image clearly shows a huge spiral of gas and dust,800 LY across,which is
fueling the BH. Is the size of the BH relative to the size of the
galaxy that it has created? Bert
