Did the ancient Egyptians have electricity?

How did ancient Egyptian had light inside their temples?

Many questions where moving inside my head, especially if you visited a tomb or went inside the pyramids, how could they see inside their tombs to draw paintings without electricity, no yet nowhere on the ceilings it there even the slightest evidence of soot or smoke residue, How then torches were used by the ancient Egyptians to light the pitch black chambers of tombs and temples According to most mainstream archaeologists, Also, there isn’t enough oxygen inside those tombs with which to support or feed a flame of a torch.
Dendera was the area where the knowledge of the light-giving source was kept, and this secret knowledge was kept by the high priests. They were the only ones that were privy to this type of information, because Dendera was the special place where this specific knowledge was guarded and kept.

Dendera Temple is located about 2.5 km south-east of Dendera, Egypt. It was part of a temple complex, The main temple is called Hathor’s Temple

In Egypt there is this underground crypt at Dendera that was always secret and only the high priests had access to that crypt. It is very hot in there, very narrow, low ceiling, and on the walls you have these reliefs of what looks like ancient light bulbs.

The walls are decorated with human figures next to bulb-like objects reminiscent of over sized light bulbs. Inside these “bulbs” there are snakes in wavy lines. The snakes’ pointed tails issue from a lotus flower, which, without much imagination, can be interpreted as the socket of the bulb. Something similar to a wire leads to a small box on which the air god is kneeling. Adjacent to it stands a two-armed djed pillar as a symbol of power, which is connected to the snake. Also remarkable is the baboon-like demon holding two knives in his hands, which are interpreted as a protective and defensive power.
