Michael Faraday's made a light bulb with a platinum wire, he put it in a small glass globe, and attached it to a low voltage source. it glowed and produced light.
Platinum is expensive. It only worked at low voltage.
Others made lightbulbs.
Edison decided a light bulb was a good idea but it needed to be made inexpensively. It needed to work at a higher voltage. The source of the electricity needed to be different from the place where the light bulb would be used.
He looked for a material that could be made inexpensively and could last. It needed to be able to take higher voltage. He heated some thread until it turned to carbon. Then he made a vacuum inside a light bulb. He put the thread inside the bulb. It worked.
He created a light bulb. It could be made inexpensively. It could work at a fairly high voltage.
Thomas Alva Edison invented the light bulb in 1877.
The computer was not invented by Thomas Alva Edison. He is best known for inventing the phonograph, the electric light bulb, and the motion picture camera.
Thomas Edison created the first commercially practical incandescent light bulb in 1879. He improved upon existing designs to create a longer-lasting bulb that could be mass-produced and widely used for practical purposes.
Thomas Edison is credited with inventing the first commercially viable incandescent light bulb in 1879. However, others had developed earlier versions of the light bulb before him.

someone, but he IMPROVED the light bulb as well so... it wasnt the same for long
