Before 20th Century

"Before creation itself, there were six singularities. Then the universe exploded into existence, and the remnants of this system were forged into concentrated ingots... Infinity Stones."

- Collector

This is a timeline of events that occurred before the 20th century.

c. 13,800,000,000 B.C.

 * As the universe came into existence, six pre-existing singularities were formed into the six Infinity Stones (Space, Mind, Reality, Power, Soul, and Time) by the Cosmic Entities.

c. 80,000,000 B.C.
"Millions" would technically refer to a minimum of 2 million years, and a maximum realistically of 9.99999. It can be up to 19.99999, which is just before it becomes "tens of millions", so a weighted average means the maximum is roughly 13.33333 million years. This would mean that "millions" strictly refers to approximately, to find the midpoint, (2 + 13.33333) ÷ 2 = 7.66667 million years. However, it is rare for people to refer to "tens of millions" or "hundreds of millions", and this needs to be taken into account - that Ego may simply be referring to any number ending in "millions" (be it units, tens, or hundreds). The middle of these is tens of millions, which is absolute minimum 10 and realistic minimum 20, to realistic maximum 99.99999 and absolute maximum 199.99999. Therefore, with weighted averages, it is roughly minimum 16.66667 million years, maximum 133.33333 years, and the midpoint of these is (16.66667 + 133.33333) ÷ 2 = 75 million years. Finally, averaging these two figures, you get around (7.66667 + 75) ÷ 2 = 41.33333 million years as an approximation for the term "millions". Ego then later says "millions and millions". This is also a hard number to quantify, but can be boiled down to either meaning "millions + millions" (so × 2), or "millions on top of millions", like building to the power of 2 (so × 2², or × 4). From this, one could say that it is around × (2 + 4) ÷ 2 = × 3. Therefore, one could approximate that "millions and millions" means roughly 41.33333 × 3 = 124 million years. The average of these two is then (41.33333 + 124) ÷ 2 = 82.66667 million years, meaning overall that Ego was born very approximately 82,666,666.66667 years before 2014. This gives roughly 82,664,653 B.C. - or c. 80,000,000 B.C. to 1 significant figure (to signify that it is a very rough approximation). The Celestial scenes shown by the Collector in Guardians of the Galaxy can be assumed to have occurred around the same era.
 * The Celestials use the Power Stone to impose judgment upon enemy civilizations. Over time, the Cosmic Beings are overwhelmed by the Stone's power and attempt to dispose of it by encasing it in an Orb and storing it away in the Temple Vault on Morag. In Guardians of the Galaxy Vol. 2, Ego says he has been building his planet, since he came into existence, for "millions of years".
 * The Celestial Ego is born. After gaining self-consciousness, Ego creates layers of matter around himself, eventually forming a new planet over millions of years. Ego explores the universe in an attempt to find life besides himself, but feels disappointed in what he finds. Eventually, he begins planting seeds on many of these worlds, with the intent of one day using them to absorb all life until only he remains.

c. 2,500,000 B.C.

 * A meteorite made of vibranium strikes the east of the continent which would come to be known as Africa. It affects the plant life around it, imbuing it with strength, prosperity, and mysticism.

c. 30,100 B.C.

 * A Chronicom begins its life. Thousands of years later, it would assume the identity of "Enoch".

c. 28,000 B.C.

 * The Chronicom agent later to be known as Enoch is sent to Earth to study the evolution of the human race.
 * As the time of human intelligence comes, five tribes in East Africa settle on the land where the vibranium meteor struck and call it "Wakanda".

c. 10,000 B.C.

 * The five tribes of Wakanda live in constant war with each other until, one day, a warrior shaman named Bashenga receives a vision from the panther goddess Bast, who leads him to the Heart-Shaped Herb. Bashenga ingests the plant and it grants him superhuman strength, speed, and instincts. He becomes king and the first Black Panther, the protector of Wakanda. While four of the tribes agree to live under Bashenga's reign, the Jabari Tribe instead choose to isolate themselves in the mountains.

7353 B.C.

 * Buri, the first king of Asgard, is born.

c. 5700 B.C.

 * Agamotto forms the Masters of the Mystic Arts as a league of magic practitioners, dedicated to learning Magic so to safeguard the Earth from dimensional evils.

5244 B.C.

 * Bor Burison is born to Buri, king of Asgard.

c. 3500 B.C.

 * In order to raise their chances in the war against their enemies, a rogue Kree faction visits numerous planets, genetically altering a number of sentient life forms in order to create biological weapons. One of the planets visited is Earth, and the Kree's experiments give rise to an unique caste of genetically altered Humans. When these humans are deemed ready for war, the Kree expose them to Terrigen Mist, which activates their special genetic ability of Terrigenesis; a process which imbues the human with a power unique to them. They construct the Diviners, containment devices built to hold Terrigen Crystals. The Diviners will only open if one of these genetically altered humans brings them to a cityscape built beneath the planet's surface, releasing the mist so as to "divine" those who have the altered Terrigen Gene. The Kree hierarchy discovers the faction's illegal activities and the operation is abandoned. The Kree disperse from Earth, leaving behind six Diviners, the city, and at least one of their deceased kin. These genetically altered humans eventually start to call themselves "Inhumans".
 * A powerful Inhuman, referred to as Alveus, is created by the Kree to dominate the rest of his race, but eventually overpowered his own creators and banished them from Earth. The humans and other Inhumans, afraid of his powers, banished him to a distant planet through a Kree Monolith. Followers of the exiled Inhuman founded a secret society and start planning its return to Earth in order to let him rule it.
 * On the distant planet, the Inhuman finds nine powerful and advanced, yet very divided, civilizations. The Inhuman consumes all life in these civilizations until they are completely wiped out.

3480 B.C.

 * Odin Borson is born to Bor Burison, becoming the heir to the throne of Asgard.

3460 B.C.

 * Odin defeats Surtur in battle. The Fire Demon would then spend nearly 5500 years recovering in Muspelheim, before his encounter with Odin's son, Thor, in 2017.

2988 B.C.

 * The Convergence occurs. The gravitational anomalies that it causes allows the construction of several megalithic monuments, particularly Stonehenge.
 * First Battle of Svartalfheim:
 * The Dark Elves led by Malekith try to destroy the Nine Realms with the power of the Aether, the Reality Stone. They are stopped by the Asgardian army led by Bor, who successfully seized the Aether.
 * In an effort to save his race, Malekith kills most of his army and much of Bor's army, then puts his remaining forces into a sleep which lasts for millennia. Bor orders for the Aether to be hidden in the deepest area possible, where no one can access it.

679 B.C.

 * Hela Odinsdottir is born to Odin Borson, becoming the rightful heir to the throne of Asgard as his firstborn.

659 B.C.

 * Subjugation of the Nine Realms: As Hela reaches adulthood, she begins to fight alongside her father, Odin. Over the years, together, they build Asgard's empire across the realms and build its glory.Cate Blanchett is quoted as saying that Hela was imprisoned for 5000 years. This is not quite possible, as in Thor: The Dark World, Odin says, "We are not gods. We are born, we live, we die. Just as humans do," to which Loki replies, "... Give or take 5000 years." The implication from this is that Asgardians live approximately 5000 years longer than humans, and this matches what we see in Thor, where Odin is shown to be roughly a decade or so younger in 965 A.D. than in 2010, 1045 years later - also proving that Odin does not have an especially long lifespan. Loki's dialogue also matches nicely with the understanding that Asgardians age at a normal human rate until adulthood before slowing down significantly, as it lines up perfectly with Chris Hemsworth and Tom Hiddleston's ages when calculated. For Hela to have been imprisoned for 5000 years, she would have to have been a child when imprisoned, and an elderly woman now - and even if she had not aged in her imprisonment for whatever reason, she would have to be a few thousand years old when she was imprisoned, which would have been only a few hundred years after Odin, her father's birth. Overall, it can be assumed that Blanchett is rounding up, intending "a few thousand years". The earliest this event can possibly be, with Hela's date of birth calculated for early 679 B.C. (see other references), is Hela beginning fighting with her father in 659 B.C., when Hela is 20 (by both human and Asgardian age, the approximate age at which Asgardians reach adulthood), and then 639 B.C., after about a minimum of 20 years of building the empire, for her imprisonment - only 2655 years before Thor: Ragnarok.

639 B.C.

 * By the time Odin decides to stop his conquest after realising peace is the true way to unite the Nine Realms, Hela's ambition has grown too large, and coupled with her tremendous powers, she ultimately tries to take the throne and Odin is forced to battle and imprison his daughter in the realm of Hel after defeating her, for the safety of the Asgardians. There she was kept for nearly 2700 years, until her escape in 2017. Odin would spend the next several centuries burying her history and pretending she never existed. When his next child, Thor, was born over 1600 years later, he claimed him to be his actual firstborn.

Her father and the man who imprisoned her, Odin, sends his army of Valkyries on their flying steeds to keep her at bay. They attempt to prevent her escape, but Hela is too much for them and she massacres the whole army, save for Brunnhilde, who is saved by one of her teammates. Odin intervenes and enters Hel. The All-Father manages to overpower and reimprison Hela.
 * Brunnhilde forsakes Asgard and escapes to the junk planet of Sakaar, where she intends to live out the rest of her days drinking and salvaging, attempting to leave her old Valkyrie life behind her.

964 A.D.
