Petroleum was formed from organisms living in the sea.

As these organisms died, their bodies settled at the bottom of the sea.

These bodies got covered with layers of sand and clay.

Over millions of years, in the absence of air, and under high temperature and pressure the dead bodies are converted into petroleum and natural gas.
