In reality, a lot of the most important gods of folklore were those with the power to wield electrical power in the form of lightning: Zeus for the GreeksTlaloc for the AztecsIndra for the HindusThor for Norse mythologyRaijin for the Shinto in Japan (celebrated as Raiden in the Mortal Kombat computer game franchise)While there might have been some close calls along the roadway to discovering how to make electrical energy work for mankind, it wasn’t till around 1600 that considerable steps towards understanding electromagnetism were made.
