This may sound silly - but "by looking up in the sky".
Supernova SN185 remained visible in the night sky for eight months
By Chinese astronomers in 185 AD
The first recorded supernova was observed by Chinese astronomers in 185 AD, which is known as SN 185. However, the discovery of the first modern supernova, SN 1572, was made by the astronomer Tycho Brahe in 1572.
The earliest recorded supernova was observed by the ancient Chinese astronomers in 185 AD. The supernova, now known as SN 185, was visible in the night sky for several months.
The word supernova was first used by Fritz Zwicky, a Swiss astrophysicist and astronomer, and was first seen in print in 1926. The word was from the original German, Haupt Nova.This comes from Nova (plural novae) which means "new" in Latin.
From 1400 BC to AD 1600, China recorded around 90 novas. Among them the supernova SN1054 [See Link] was the first supernova confirmed by modern radio astronomers. A British astronomer in 1731, discovered an oblong cloud"" over China. After observation, calculation and analysis by several astronomers, it was proved that the crab shaped nebula found in this position was the ruins of a supernova that had shot out of a dense cluster some 900 years previously. i.e. the year of 1054. This discovery was one of the most significant astronomical findings in the 1960s.

Yes, the first neutron star was observed in a supernova remnant. The object, named PSR B1919+21, was discovered in 1967 in the Crab Nebula, the remnant of a supernova that exploded in the year 1054 AD.

SN185, the first supernova recorded by Chinese astronomers in 185 AD, is estimated to be 8200 lightyears away from us. As such, the actual time of the explosion is estimated to be 8015 BC.Since large astrometric distances are measured in light years, it is not necessary to know the speed of light or use it in any calculation, for the purposes of answering this question.
