Ah, but others before Edison had tried to create one. His was just the first practical one that could be mass produced. And even before then Humphrey Davy had demonstrated an electric arc light sometime betwen 1802 and 1809 so the concept of an electric light wasn't unknown when Edison took up the challenge.
