When gases coalesced to form petroleum, 'people were drowned in a sticky substance raining from the sky', in the words of the Mayas' sacred book, Popol-Vuh. Elsewhere, the petroleum was ignited by oxygen in the Earth's atmosphere, and a terrible deluge of fire was recorded from Siberia to South America.

Could you image it raining gasoline! I think we got it good these days lol!
