The first practical incandescent light bulb. Edison and his team of researchers in Edison's laboratory in Menlo Park, N.J., tested more than 3,000 designs for bulbs between 1878 and 1880. In November 1879, Edison filed a patent for an electric lamp with a carbon filament.
because if he didn't make the light bulb we would be living in the dark and the only source of light would be daylight
There are a number of discoveries and works that are credited to Thomas Edison. Some of them include the motion picture camera, electric light bulb, phonograph and so many more.
Thomas Edison's light bulb was special because it was one of the first practical and commercially viable electric light sources. His improvement over earlier designs included a carbon filament that could last for over 1,200 hours, making it more durable and efficient. Edison's development of a complete electrical system, including generators and wiring, allowed for widespread adoption of electric lighting, transforming everyday life and paving the way for modern electrical infrastructure.

I'm sorry to say that he didn't In 1878 Joseph Wilson Swan, an English physicist and Chemist received a patent for his invention and his house was the first in the world to be lit by electric light. See Swan's Wikipedia entry Thomas Edison,upon seeing the British patent,or open letter, made copies and publicised his work. Swan was keen to make money from his invention and decided set up a joint venture which became the 'Ediswan' company in 1883. I am sure the name Swan would not have figured in the name unless Edison was forced to retract his claim of prior invention. Edison did produce an efficient steam driven DC dynamo known as' Long Waisted Annies' to drive his lamps and famously lit the road out side his workshop. This the likely source of your error.
one of thomas edisons inventions were the phoneograph and ther light bulb
The Light Bulb
yes. xzavier jackson and armonie taylor improved thomas edisons light bulb invention with a fan.
It is likely that Thomas Edison's best invention in the incandescent light bulb. It led to a massive surge in productivity in the 20th century in all industries.

Edison's most famous invention was the electric light and the system for powering it.

Some may think it was the light bulb, but Edison had so many inventions. He also did the phonograph. He also did an early movie projector called the kinetoscope.

No, the first light bulb that Thomas Edison invented is not still operational. Over time, light bulbs burn out and lose their ability to produce light due to the filament burning out. However, Edison's invention laid the foundation for modern lighting technology.
