Why can the ever-burning lamp last for thousands of years?

Ancient tombs are often frequented by tomb raiders, and the ever-burning lamps of ancient tombs were first discovered by tomb raiders. These tomb raiders often have unique skills, and their skills in tomb raiding are superb. It is their housekeeping skills to divide the money, watch the geomantic omen and explore the terrain.

Presumably, everyone has seen some TV dramas and movies about tomb robbery. Among them, the tombs people see are often dark and opaque, and the organs are heavy, and they are killed if they are not careful. However, this often brings more curiosity and thrills to the audience, especially the gorgeous coffins and countless gold and silver treasures in the tomb, which are full of our visual sense and leave a deep impression on many of us.

In a closed environment, if the lamp is still burning, oxygen is gradually consumed, and it cannot continue to burn without enough. In a closed environment for a long time, part of the lamp oil is volatilized, and the body of the dead is produced by microorganisms, which will not burn without oxygen.

Everything is in a constantly changing space, and it is the same truth that the seasons alternate, so the lamp is not immortal as people think. When the entrance to the tomb is opened, the air will also enter the tomb, and oxygen will spontaneously ignite, so the lamp will be rekindled, so what people see is that the lamp is burning. This kind of long-lasting lamp is also hoped to be made in the future and the immortality that human beings are constantly pursuing will also be realized.
