Is God empirical or non-empirical to you?
I may define a God concept as "God created Everything, you live-in" or you may define and/or choose a God concept as per your wish to answer.
Belief can be based on observation and experimentation (empirical) or it can be blind/with no base (non-empirical).
non-empirical ( blind/with no base) means: for example,
If God created everything,
then the creator God is not within everything,
therefore, God cannot be observed and/or experimented within everything,
Else you step outside-the-box (everything).
God can be observed and/or experimented (God becomes empirical).
It is possible for a true theist and/or true atheist (not the stupids who deny, with no consideration to concept), to see God empirically.
