Satan went by other names but in India there are towns named Satanama and other names too. Satya, Satyan means Eternal Truth in Sanskrit. This God was global. There were other Gods too. They gave humanity knowledge like agriculture, math, science, astronomy, meditation, writing. christianity took our original Pagan Gods and turned them into monsters and demons. This was done to Satan who was known by a different names before this but when they mention Satan, they are referring to this pre-christian Pagan God. So the name works. It is not blasphemous. Satan means enemy or Adversary in hebrew. The jews created christianity and islam to pretty much destroy everything. the abrahamic religions are negative religions.
