From top left clockwise: The Temple of Ġgantija, one of the oldest freestanding structures in the world; Warka Vase; Bronocice pot with one of the earliest known depictions of a wheeled vehicle; Kish tablet, an example for proto-writing; Pharaoh Narmer is credited with uniting Upper and Lower Egypt and is depicted as such in the Narmer Palette.
The 4th millennium BC spanned the years 4000 BC to 3001 BC. It marked a critical turning point in human history, characterized by the transition from late Neolithic agricultural societies into urban, state-level civilizations.
This millennium witnessed the invention of writing, the initial spread of bronze metallurgy, the adoption of the wheeled vehicle, and the rise of the first primary states in Mesopotamia and Ancient Egypt, effectively initiating recorded history.
World population growth relaxed after the burst that came about from the Neolithic Revolution. World population was largely stable in this time at roughly 50 million, growing at an average of 0.027% per year.
The cuneiform script proper emerges from pictographic proto-writing in the later 4th millennium. Mesopotamia's "proto-literate" period spans the 35th to 32nd centuries BC. The first documents unequivocally written in the Sumerian language date to the 31st century BC, found at Jemdet Nasr.

3300–3000 BC: Evidence of proto-Thracians or proto-Dacians in the prehistoric period; Proto-Dacian or proto-Thracian people developed from a mixture of indigenous peoples and Indo-Europeans from the time of Proto-Indo-European expansion in the Early Bronze Age.
3600 BC – Construction of the Ġgantija megalithic temple complex on the Island of Gozo: the world's oldest extant unburied free-standing structures, and the world's oldest religious structures. (See Göbekli Tepe for older, buried religious structures.)
3600–3200 BC – Construction of the first temple within the Mnajdra solar temple complex, containing "furniture" such as stone benches and tables, that set it apart from other European megalith constructions.
Great Neolithic Plague occurs from circa 5450 BC to circa 2700 BC. This ensures for the large scaled expansions of the later early bronze age.
The Post Track, an ancient causeway in the Somerset Levels, England, is built, c. 3838 BC. It is one of the oldest engineered roads discovered in this part of Europe.
Neolithic Chinese settlements. They produced silk and pottery (chiefly the Yangshao and the Longshan cultures), wore hemp clothing, and domesticated pigs and dogs.
c. 3600 BC – Evidence of maize domestication appear in the Valley of Tehuacán. First known evidence of popcorn. Excavations of the Bat Cave in west central New Mexico in 1948 and 1950 discovered ears of popcorn dated to circa 3600 BC.
Sub-Saharan Africa remains in the Paleolithic period, except for the earliest neolithization of the Sahel following the desiccation of the Sahara in c. 3500 BC. As the grasslands of the Sahara began drying after 3900 BC, herders spread into the Nile Valley and into eastern Africa (Eburan 5, Elmenteitan). The desiccation of the Sahara and the associated neolithisation of West Africa is also cited as a possible cause for the dispersal of the Niger-Congo linguistic phylum.
The Older Peron transgression was a period identified in 1961 happening between 6,000 and 4,600 years BP when sea levels were 3 to 5 metres higher than today.

3929 BC – Creation according to John Lightfoot based on the Old Testament of the Bible, and often associated with the Ussher chronology.
3761 BC –
Since the Middle Ages (12th century), the Hebrew calendar has been based on rabbinic calculations of the year of creation from the Hebrew Masoretic Text of the bible. This calendar is used within Jewish communities for religious and other purposes. The calendar's epoch, corresponding to the calculated date of the world's creation, is equivalent to sunset on the Julian proleptic calendar date 6 October 3761 BC.
25th of Elul, 7 October 3761 BC — Considered the first day of creation from formless matter (Gen. 1.2), traditionally interpreted as out of nothing, on which the Bible recalls that God created existence, time, matter, darkness and light.
1st of Tishrei, 12 October 3761 BC — Considered the sixth day of creation (Rosh Hashanah Day 1), on which the Bible recalls that God created Adam and Eve.
3102 BC – According to calculations of Aryabhata (6th century), the HinduKali Yuga began at midnight on 18 February 3102 BC. Lasting for 432,000 years (1,200 divine years), Kali Yuga began 5,127 years ago and has 426,873 years left as of 2026CE. Kali Yuga will end in the year 428,899 CE.
3102 BC – Aryabhata dates the events of the Mahabharata to around 3102 BC. Other estimates range from the late 4th to the mid-2nd millennium BC.
Notes
↑Calculations exclude year zero. 1BCE to 1CE is one year, not two.
