Thomas Edison invented the first light bulb.

False. Although Thomas Edison patented a greatly improved and commercially viable light bulb in 1879, he was not the first. Several inventors, such as Humphry Davy in 1802 and Joseph Swan in the 1860s, had created working light bulbs before Edison. Edison's major contribution was making it practical, inexpensive, and long-lasting for mass production, leading to its global spread and a revolution in lighting.
