Halley's Comet, if it is a typical comet, was created during or shortly after the formation of the solar system, some 4.6 billion years ago. Although it may have originally had a very elliptical (long-period) orbit, the current (short-period) orbit may have been established between 10,000 and 200,000 years ago. It has been observed from Earth since about 240 BC (about 2250 years) and last appeared in the inner solar system in February, 1986.
Now I'm no expert but I'd say the history was passed down through generations.

Remembering that there was no year zero, it was 4643 years between 2630 BC and 2014 AD.
As of 2016, the year 18,000 BC was 20,016 years ago.
The year 1233 BC was approximately 3,253 years ago.
BC+AD= time elapsed 530+2011= 2541 years ago
2022
