REFUTED
the evidence says no
Recorded sources
0 sources for · 9 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that Thomas Edison invented the first incandescent light bulb?

No. Multiple reference and peer-reviewed sources state that incandescent lamps existed before Edison and that the incandescent bulb was invented by Joseph Swan and Edison together, while others credit Edison only with a practical or commercially viable bulb.
