Hello there, and welcome to FFI
First, ALL religions and their gods, without exceptions are man made. Any religion you chose, is unreal, made up by humans, for the sole purpose of controlling others.
There are no gods, except in people's minds.
You say that the government doesn't recognize atheism. Your beliefs, or lack thereof is not the government's business. Your mind is your own.
Again, welcome and keep posting.
