How the world came to be, and where it's heading
A compressed timeline of the milestones that produced the world the globe shows today: the universe, the planet, life, humanity, civilization, and the modern era, then a look forward at where the trends are pointing.
Facts only. Deep-time dates follow the scientific consensus (cosmology, geology, paleontology, archaeology); historical dates follow standard history. Future entries (amber dots) are projections from named institutions, not predictions of this site, the future is uncertain and these are central estimates that will change.
I · The Universe & the Earth
13.8 billion to 4 billion years ago · cosmology & geology
13.8 billion years ago
The Big Bang. Space, time, matter and energy begin; the universe expands and cools. (Planck/cosmology consensus)
13.6 billion years ago
The first stars and galaxies ignite, forging the first heavier elements. The Milky Way begins to assemble.
4.6 billion years ago
The Sun and Solar System form from a collapsing cloud of gas and dust.
4.54 billion years ago
Earth forms. Soon after, a Mars-sized body strikes it; the debris coalesces into the Moon.
4.4 billion years ago
Earth cools enough for the first liquid-water oceans to form.
II · The Rise of Life
3.7 billion to 300,000 years ago · paleontology
~3.7 billion years ago
The earliest life, single-celled microbes, appears in the oceans.
~2.4 billion years ago
The Great Oxygenation Event: photosynthesizing microbes fill the air with oxygen, remaking the planet's chemistry.
~540 million years ago
The Cambrian Explosion: complex multicellular animals diversify rapidly in the seas.
~230 million years ago
The first dinosaurs appear; they dominate the land for over 160 million years.
66 million years ago
An asteroid impact ends the age of dinosaurs. Mammals rise to fill the gap.
~7 million years ago
The human and chimpanzee lineages split; early hominins begin walking upright in Africa.
~300,000 years ago
Homo sapiens, anatomically modern humans, emerge in Africa. (oldest known fossils: Jebel Irhoud, Morocco)
III · Humanity & the First Civilizations
70,000 BCE to 1 CE · archaeology & ancient history
~70,000 years ago
Humans begin migrating out of Africa, eventually populating every continent except Antarctica.
~10,000 BCE
The Agricultural Revolution: humans domesticate plants and animals, settle down, and form the first villages.
~3,400 BCE
The first cities and writing arise in Mesopotamia (Sumer). Recorded history begins. Egypt's pyramids follow ~2,600 BCE.
~500 BCE to 500 CE
Classical civilizations flourish: Greece, Rome, Persia, Maurya India, and Han China. Major world religions and philosophies take shape.
IV · The Making of the Modern World
500 to 2000 CE · recorded history
1440s
Gutenberg's printing press makes knowledge mass-reproducible, accelerating the Renaissance and Reformation.
1492
Columbus reaches the Americas, beginning the Columbian Exchange, the linking (and upheaval) of the world's continents.
1760s-1840s
The Industrial Revolution in Britain harnesses coal and machines, launching sustained economic growth for the first time in history.
1914 to 1945
Two World Wars reshape the global order. The atomic age begins (1945); the United Nations is founded.
1947 to 1991
Decolonization creates dozens of new nations; the Cold War between the US and USSR ends with the Soviet collapse in 1991.
1990s
The World Wide Web goes public, connecting humanity into a single information network.
V · The World Today
2000 to 2026 · the era the globe measures
2007 to 2008
The smartphone (iPhone, 2007) puts the internet in everyone's pocket; a global financial crisis reshapes economies.
2020 to 2023
The COVID-19 pandemic kills millions and disrupts the global economy; recovery follows with high inflation.
2022
Russia invades Ukraine, Europe's largest war since 1945, and generative AI (ChatGPT) reaches the public.
2025 to 2026
World population ~8.25 billion; output ~$115 trillion. A Gaza ceasefire (Oct 2025) and record conflict counts coexist; AI investment tops $400B/yr; CO₂ passes 430 ppm. (the state of play shown on the globe)
VI · Where It's Heading
2030 to the far future · projections from named institutions (not certainties)
2030
Target year for the UN Sustainable Development Goals; India projected to be the world's 3rd-largest economy. (UN; IMF)
~2050
World population projected to reach ~9.7 billion, with over half of growth in sub-Saharan Africa. Many nations target net-zero emissions. (UN WPP; national pledges)
~2080s
Global population projected to peak at ~10.3 billion, then begin a slow decline as birth rates fall worldwide. (UN WPP 2024)
2100
Warming projected between ~1.5°C and ~3°C+ above pre-industrial levels depending on emissions choices this century. (IPCC scenarios)
Deep future
In ~1 billion years the brightening Sun likely ends complex life on Earth; in ~5 billion years the Sun becomes a red giant. Humanity's long-term path may lead off-planet. (stellar physics)
