The short version: in the beginning, there was nothing, which then exploded.
The longer version: all the matter in the universe was compressed into the smallest possible volume. Try to understand that this is so much matter that the force of gravity warps the laws of physics as we know them. The whole thing is is under so much pressure that it explodes – forming the universe as we know it as the laws of physics change radically from picosecond to picosecond, and eventually energy cools and congeals into matter.
It’s like they say: “it all started with the Big Bang”
The majestic oceans of planet Earth were formed neither quickly nor simply. It took literally millions of years between the first surface water’s appearance and the creation of the primordial sea.
Several factors contributed to this: the gradual cooling of the Earth was the first and most important, but also important was the slow release of water from existing minerals, the condensation of steam, and even the addition of water in the form of ice from occasional cometary collisions with the planet.
The first waters soon became the habitat of early prokaryotes – whose biochemical processes led to the formation of still more water. Indeed, it is possible that the majority of water on the planet today exists as a result of these organisms.
Everyone loves the dinosaurs. A lot of people – if the Jurassic Park films are to be believed – would like to see them come back. But without their extinction, we wouldn’t be here today.
Even now, it’s still not clear what exactly caused the extinction event – but the best known hypothesis is that of Luis and Walter Alvarez, which states that a meteoric or cometary impact caused a nuclear winter-like effect that altered the climate drastically, wiping out something like 75% of all species alive at the time. The effects were particularly felt by larger species – which included most dinosaurs.
In the wake of the event, now open evolutionary niches were occupied by mammals and birds, including our own ancestors.
Note: there is no dated entry for today’s date, so I have chosen instead to include an event which, although it manifestly occurred, is impossible to date.
Not actually true mammals, but instead mammaliformes, the members of the sub-class Allotheria are distinguished from other mammals chiefly by their dentition, which featured lower molariform teeth equipped with two longitudinal rows of cusps. Extant from the Late Triassic through to the Early Oligocene, the Allotheria were rodent-like animals in appearance.
They were widespread, found on all continents including Antarctica (which was considerably warmer in this era), and included in their ranks herbivores, carnivores and omnivores. Unfortunately for biodiversity, the last of them died out between 33.9 and 28.4 million years ago, give or take 100,000 years.
The classic ‘caveman’, Neanderthals – homo neanderthalensis – were native to Europe, Western Asia and Central Asia. The earliest Neanderthal characteristics evolved at around this time – fossil evidence (admittedly incomplete) suggests that the full differentiation of the species had taken place by 130,000 BCE.
They were not, as is often thought, the ancestors of modern humanity, but rather a rival species that our ancestors wiped out in a competition for space and resources.

In the traditions of the Indigenous Australian peoples, their ancestors were created with the land, at the dawn of what is called the Dreamtime, the Dreaming or Alterjinga.
Science tells it a little differently. The original ancestors of the people now known as the Australian Aboriginals emigrated to Australia at some point between 40,000 and 120,000 years ago. Due to the wide variation of dates, it is unclear whether they arrived here after a sea crossing, or via a landbridge now submerged. It is not known where they first set foot in Australia, nor how many separate waves of migration occurred.
What is for certain is that these people dwelt in Australia with little or no contact with the rest of the world (the Macassar fishing fleets being one of the few exceptions), for thousands of years before European settlement in 1788. Whether or not one accepts the Dreamtime legend, there remains an undeniable case for considering them to be the traditional owners of the land, displaced and disenfranchised by European imperialism.
The most recent Ice Age – or more precisely, the most recent glacial maximum of the current Ice Age – ended a little under 10,000 years ago, having lasted some 70,000 years itself. The abrupt climactic changes (abrupt in a geological sense) contributed to mass extinctions of various animal species, notably the woolly mammoth, although it is also believed that hunting by early humans also contributed to at least some of these extinctions.
In geological terms, the end of the last Ice Age is recorded as the transition from the Pleistocene to the Holocene epochs.
It’s Atlantis. Everyone knows the basics: an advanced civilisation on a large island or small continent in the Atlantic Ocean, sunk beneath the ocean in a single day.
The Atlantis story originated in two works by Plato, the Critias and the Timaeus. These tell the story of Atlantis – created by the sons of Poseidon, ruled the world as an economic superpower, and finally destroyed by the gods of Olympus for its hubris.
Of course, so far as anyone can tell, Atlantis never truly existed. It was a myth, a parable regarding the dangers of arrogance and pride.
Pity, really.

It’s not clear exactly when Cain murdered Abel in any biblical chronology I’ve been able to find. Some of them even date it (as I have here) to 4004 BCE, the same year usually given for the Creation of the earth. Which implies that not only were Cain and Abel both full grown men in the space of a single year, but that their mother’s two pregnancies (Cain and Abel were not twins – Cain is the older), also took place in that same year.
Nevertheless, as brothers, they didn’t always get along. This may or may not have had something to do with the notoriously fickle and hard to please deity that they worshipped, or that deity’s changing of the rules on them – Cain presumably would not have made an offering that God (who is, according to the Gospel of Luke, Cain’s grandfather) that God found unacceptable had he known ahead of time that it would be rejected.
Cain responds to his rejection by God by hunting and killing his brother, Abel. (Which makes him sound a little older than >1 – about 16 or so, I would guess.) And then God, not done with the mind games, pretends not to know about it and questions Cain, leading to his infamous declaration that he was “not his brother’s keeper” (which is a rare concession to historical accuracy by the Book of Genesis – cricket had indeed not yet been invented). God curses Cain and exiles him, making him the earliest biblical figure to be set up and knocked down by God.
Imhotep was an Egyptian polymath who was what we would later call a Renaissance man. Of course, Imhotep had a 4000 year headstart on Leonardo. He served the Third Dynasty pharoah Djoser as vizier, although the complete list of his titles ran: Chancellor of the King of Egypt, Doctor, First in line after the King of Upper Egypt, Administrator of the Great Palace, Hereditary nobleman, High Priest of Heliopolis, Builder, Chief Carpenter, Chief Sculptor and Maker of Vases in Chief.
His most notable work to modern eyes is the Step Pyramid of Saqqara, in which the pharoah Djoser was buried. It was the first pyramid, and comparitively small and primitive, but for its time it was an engineering marvel.
After his death, Imhotep was deified, one of very few Egyptians to whom this occurred (other than the pharoahs).
