Fire was energy produced by rapid oxidation. The earliest splinter of Scaroth showed mankind how to make fire (TV: City of Death) and by roughly 100,000 BC, fire had become a precious commodity, as relatively few humans knew how to recreate it once it was snuffed out; in some tribes, this knowledge was held only by a select few.
The First Doctor and his companions Ian Chesterton, Barbara Wright and Susan Foreman encountered a tribe looking for this knowledge; Chesterton ultimately showed Za, a tribal leader whose predecessor was unable to give him the secret before dying, how to make fire. (TV: An Unearthly Child)
According to Greek mythology, Prometheus stole fire from heaven and gave it to the first men. When the Fourth Doctor met Prometheus and recounted this story, the Olympian corrected him, saying that he actually stole the spark of life. (COMIC: The Life Bringer)

In 2011, when a Teselecta disguised as the Eleventh Doctor was shot by River Song in order to fake the Doctor's death, it appeared to fall dead, and a funeral pyre was lit for it by Amy Pond, Rory Williams and a future version of River, using gasoline provided by Canton Everett Delaware III. The Doctor later claimed that his doppelganger was "barely singed" by the pyre. (TV: The Impossible Astronaut, The Wedding of River Song)
