Halley's comet will next appear in the night sky in the year 2062. It orbits the sun every 75-76 years, so this is the time between appearances.
Crude oil has parts of decomposed dinosaurs and plants from millions of years ago. When the sun gave energy to the plants for their growth, the dinasours ate them which is now is stored in the oil today.
