Can coal and petroleum prepared in a laboratory by dead organisms?

Coal and petroleum are formed from ancient organic materials, primarily from plants and marine organisms, subjected to heat and pressure over millions of years in natural geological processes. While laboratory conditions can mimic certain aspects of these processes, creating coal or petroleum from scratch in a lab setting is not practical or economically viable. Instead, scientists can produce synthetic fuels or other hydrocarbons through chemical processes, but these differ from naturally occurring coal and petroleum.
