God (Paramatma, Ishwar)

There is no God, if understood as a super-human who lives in the sky or heaven, and can do magical things.

For me, the term God is a synonym to Brahm. While the term Atma is often used instead of Brahm
in the context of living beings, the term Paramatma or Ishwar or Bhagwaan is sometimes used when referring to Brahm as something that exists even beyond the visible substances and living beings. But all these terms indeed mean Brahm.
