One of the earliest galaxies known to man is the galaxy IOK-1 and is estimated due to redshift to be 12.88 billion years old, only 750 million years after the Big Bang.
The vast distances involved means that the light we see left those galaxies a long time ago.

Light-years are mainly used to specify distances to other stars and galaxies, diameters of galaxies, galaxy walls, and the like.
who discovered the galaxies who discovered the galaxies
Spiral galaxies, barred spiral galaxies, elliptical galaxies, and irregular galaxies
Elliptical galaxies are sometime called dwarf galaxies.
Yes. Far-away galaxies can be mistaken for stars and occasionally are. This is due to the galaxies being millions upon millions of light years (the distance light can travel in a year) away from earth.

no galaxies are not harmful
The two main theories of galaxy formation are the bottom-up theory, where galaxies form from mergers of smaller structures like dwarf galaxies, and the top-down theory, where galaxies form from the gravitational collapse of large gas clouds. The hierarchical model is a popular framework that combines aspects of both theories to explain the variety of galaxy shapes and sizes observed in the universe.
