Scientists believe that galaxies were formed from the gravitational collapse of large clouds of gas and dust in the early universe. As these clouds collapsed, they formed smaller structures that eventually evolved into galaxies. The exact mechanisms of galaxy formation are still an area of active research in astrophysics.
Astronomers believe that quasars represent an early stage of galactic evolution because they are extremely luminous and compact objects located at the centers of galaxies. The high luminosity of quasars is thought to be powered by accretion onto supermassive black holes. This intense accretion phase is believed to occur during the early formation of galaxies.
Galaxies began forming around 13.6 billion years ago, not long after the Big Bang that created the universe. Over time, gravity caused matter to clump together, eventually forming the galaxies we observe today.
Mister Edwin Hubble did just that, before the 1920's, many astronomers thought that our galaxy included everyobject in space, in 1924 Edwin Hubble proved that other galaxies existed beyond the milky way
Gravity.
Scientists believe that galaxies formed earlier in the universe's history, with the most distant galaxies being some of the first to have formed after the Big Bang. Studying these distant galaxies can provide insights into the early stages of galaxy formation and evolution.
Galaxies. They are just about the same now as they were then. 14 Billion years ago, astronomers believe that the "Big Bang" created matter from energy, which is how they believe galaxies were formed.

Galaxies formed from dust, matter, and energy that formed from the explosion of the universe.
Scientist believe that the universe by a giant explosion called the big bang .

They actually are. Galaxies that are only millions of light years won't show much difference - that's too short compared to the age of galaxies. But there is definitely a trend in galaxies at distances of billions of light-years. Their metallicity is lower (i.e. they have had fewer supernovas to pollute the interstellar gas), and there is a greater percentage of disc galaxies (elliptical galaxies are thought to form by the collision of disc galaxies).

Here is what i belive to be the correct awnser. If you belive in the big bang theory then you swould know the universe started from the middle and started expanding out so the closest galaxie is moving away with us but distant galaxies are also moving away from us now i dont know about how they move or what speed they move at or if theres a differnce it is possible considering some galaxies formed billions of years after our a slowley catching up with as so i belive it varies now i hope this answer your question people may edit this in future and make it easyer to understand.
There have been some suggestions that the objects called quasars might be extremely active galaxies with unusually supermassive black holes at their centers at such great distance from us that it is not possible for telescopes to resolve their galactic structure, making them just look like very bright stars (quasi-stellar objects). However this has not been verified.If these suggestions are correct, these extremely active galaxies must be so distant that the light we are seeing from them must have been emitted only a short time after the big bang began, in the initial cycle of star formation, which would make them the earliest galaxies formed and likely very young galaxies. However if they are this young these extremely active galaxies might have galactic structures so different from the galaxies we are familiar with that even if our telescopes could resolve them, we might not recognize them as galaxies.
Scientist theorize that a planet-sized object collided with earth and the moon formed
Some galaxies would be older than others; the oldest galaxies formed pretty soon after the Big Bang - the oldest known galaxy formed about 750 million years after the Big Bang.
