In 2007 analysis of cut marks on two bovid bones found in Sangiran, showed them to have been made 1.5 to 1.6 million years ago by clamshell tools, and is the oldest evidence for the presence of early man in Indonesia. Fossilised remains of Homo erectus, popularly known as the "Java Man" were first discovered by the Dutch anatomist Eugène Dubois at Trinil in 1891, and are at least 700,000 years old, at that time the oldest human ancestor ever found. Further Homo erectus fossils of a similar age were found at Sangiran in the 1930`s by the anthropologist Gustav Heinrich Ralph von Koenigswald, who in the same time period also uncovered fossils at Ngandongalongside more advanced tools, re-dated in 2011 to between 550,000 and 143,000 year. In 1977 another Homo erectus skull was discovered at Sambungmacan

In 2003, on the island of Flores, fossils of a new small hominid dated between 74,000 and 13,000 years old and named "Flores Man" (Homo floresiensis) were discovered much to the surprise of the scientific community. This 3 foot tall hominid is thought to be a species descended from Homo Erectus and reduced in size over thousands of years by a well known process called island dwarfism. Flores Man seems to have shared the island with modern Homo sapiens until only 12,000 years ago, when they became extinct. In 2010 stone tools were discovered on Flores dating from 1 million years ago, which is the oldest evidence anywhere in the world that early man had the technology to make sea crossings at this very early time.

The archipelago was formed during the thaw after the latest ice age. Early humans to travelled by sea and spread from mainland Asia eastward to New Guinea and Australia. Homo sapiens reached the region by around 45,000 years ago. In 2011 evidence was uncovered in neighbouring East Timor, showing that 42,000 years ago these early settlers had high-level maritime skills, and by implication the technology needed to make ocean crossings to reach Australia and other islands, as they were catching and consuming large numbers of big deep sea fish such as tuna.

Austronesian people form the majority of the modern population. They may have arrived in Indonesia around 2000 BCE and are thought to have originated in Taiwan. Dong Son culturespread to Indonesia bringing with it techniques ofwet-field rice cultivation, ritual buffalo sacrifice, bronze casting, megalithic practises, and ikatweaving methods. Some of these practices remain in areas including the Batak areas of Sumatra, Toraja in Sulawesi, and several islands in Nusa Tenggara. Early Indonesians were animists who honoured the spirits of the dead as their souls or life force could still help the living.

Ideal agricultural conditions, and the mastering of wet-field rice cultivation as early as the 8th century BCE, allowed villages, towns, and small kingdoms to flourish by the 1st century CE. These kingdoms (little more than collections of villages subservient to petty chieftains) evolved with their own ethnic and tribal religions. Java's hot and even temperature, abundant rain and volcanic soil, was perfect for wet rice cultivation. Such agriculture required a well organised society in contrast to dry-field rice which is a much simpler form of cultivation that doesn't require an elaborate social structure to support it.
