Evidence of Pleistocene cultures, dating from 600,000 – 130,000 BC, have been found in various parts of Thailand, from Lampang in the north to Krabi in the south. The earliest implements found were pebble tools, followed by early flake tools (300,000 – 290,000 BC), then by Proto hoabinhian pebble tools (140,000 – 13,000 BC)
Several caves or rock faces are decorated with paintings from simple handprints to complete tableaux showing scenes of hunting, fishing and dancing. These could dae back to the 4th century BC. Some are easily accessible, like those at Khao Chiang Ngam, 124 miles from Bangkok on the road to Khorat.
