For 2 billion years life on this planet was no more complex than single celled bacteria. Around 540 million years ago the fossil record starts to show many different multicelled creatures. Geologists call the rapid expansion in the diversity of life during this period the Cambrian Explosion

Known as the Cretaceous–Tertiary extinction event, many life forms become extinct including all the dinosaurs (except birds).

Flint is rare in this region, but during the Ice Age glaciers moving along the Irish Sea deposited flint on the beaches around Aberystwyth. Evidence has been found of a Mesolithic(8000-400BC) settlement just south of the harbour. Flint was fashioned into tools and weapons and is believed to have been traded with inland tribes in this area.
Copper has already been used for thousands of years but it comes form rare minerals that include native copper. Copper chemically combined with other elements is much less rare and can be released by a process called smelting. Smelting requires high temperatures, and this was now available in pottery kilns. Copper smelted for the 1st time (in Iran)

This is a period of thousands of years and defined by the use of bronze. The period starts at different times in different parts of the world depending when they acquired the technology. The technology requires some understanding of mining, minerals, smelting, high temperature kilns and metalworking. It is accompanied by the cultural and military advances that came with having access to advanced bronze tools. Smelted copper was already known for thousands of years but adding tin or arsenic made the metal much easier to work. Copper and Tin ore was not available everywhere and it is very rare to find them close to each other, so trade and transportation had to develop.
The bronze age started around 3300BC around the eastern Mediteranian and to the east of the Black Sea. Around 300 years later is was in India but it would be 700 years after that before started to spread into Europe.

Although small numbers of bronze tools have been used in Britain for hundreds of years, these are believed to have been imported. It is not until about 2100BC that the technology to create bronze is found in Britain, making bronze tools much more common.

About 2000 years after the start of the Bronze Age, furnace technology achieved even higher temperatures which allowed the smelting of iron ores which are much more plentiful.
Starting in the same area as the Bronze Age around 1300BC, the Iron Age spread out from the around the eastern Mediteranian and to the east of the Black Sea. Around 100 years later is was in India and it would be a further 200 years before started to spread into Europe.

This is a period of about 900 years which started with the ability to make smelt iron. Iron tools became more much plentiful than bronze tools were, which led to many cultural changes. It is the distinctive cultural practices of this period that define it, and it is the cultural change that followed the Roman invasion of Britain that starts to end the British Iron Age.
