Question

How did thomas edison invent the light bulb?

Answer 1

He didn't invent the bulb, he came up with a filament for the bulb that would last long enough to make it a worthwhile invention for practical minded people.

Answer 2

Apparently, the we gave the esteemed Mr. Edison credit for the invention solely because he owned a power company, later known as General Electric, and a light bulb is just a bulb without a source of electricity to light it. In reality, light bulbs used as electric lights existed 50 years prior to Thomas Edison's 1879 patent date in the U.S.
