A conventional light bulb consists of glass, metal, and gas, but no oil
A light bulb consists of a glass bulb, a filament (or LED in the case of LED bulbs), metal contacts, and inert gases like argon or nitrogen sealed inside. When electricity flows through the filament, it heats up and produces light, illuminating the bulb.
Candles, oil lamps, and gas lights mostly.

Before the light bulb, people used candles, oil lamps, gas lamps, and lanterns to provide light. These light sources were fueled by materials such as tallow, whale oil, kerosene, and gas. Additionally, people relied on natural light sources during the day, such as sunlight and fire.
No, that would not be proper. The contact point of a light bulb socket has no need of any coating. A light bulb socket that is difficult to turn a bulb in will benefit from some light oil on the bulb threads prior to installing. Dielectric grease will harden, and is meant to insulate and protect electrical junctions from exposure and vibration.
Yes, we could still live without the light bulb as there are alternative sources of light such as candles, oil lamps, and natural daylight. The light bulb has made life more convenient and efficient, but it is not a necessity for survival.
