The Marvel Universe (AKA Earth-616) is the main universe of the Marvel superheroes published by Marvel Comics.

History

The universe itself had gone through various cycles of death and rebirth with the world of Earth-616 existing within the timeline of the eighth incarnation of the universe. After the death of a previous universe, a big bang created a eighth incarnation of reality, known today as Universe 616 (designated by various multiversal entities). The only survivor of the previous universe was the entity Galen, who then became the being known as Galactus. Across space, many mighty and significant races were born, including the Celestials, the Watchers, the Kree, the Shi'ar, and the Skrulls, to name a few. There would also be a multitude of gods and ancients, many from other realms most likely created around the same time as the universe such as the Nine Realms and the Dark Dimension (though it is possible that they have existed for longer)

After some time, the planet Earth would be created, which would have a tremendous impact on the universe as a whole. There is evidence that the immensely powerful cosmic beings known as the Celestials visited Earth in it's earliest days and most likely had a profound impact on the life that was evolving there at the time, creating the x-gene that would evolve humans into mutants. They also gave rise to two notable powerful races; the Eternals (God-like beings resembling humans) and the Deviants (whose bodies were greatly mutated, with very few looking similar).

Later, the Kree visited the planet, after being made aware of the Celestials interest in the planet and performed similar experiments on the native life. The Cotati, a race of plant-like aliens, and the Skrulls, a group of shapeshifting aliens, also visited Earth and the Skrulls held a contest of resourcefulness and world building to see which of the two races would be allowed access to their superior technology.
