Here is why you should believe in God.

[Duty]

I take it you are unable to answer my question Klorophyl? It was the first reply in this thread...

I thought your question is off-topic. I am merely arguing for a supernatural, powerful, intelligent entity, and not any specific kind of deity in any religion.

Those features alone do not meet the criteria of "God" as described in any religion or religious tradition. Most importantly it needs to be able to interfere in human affairs and also give a fuck so as to be inclined to do that. The Spanish flu epidemic of 2018, the Tsunami of 2004, congenital birth defects, childhood cancers, paedophiles etc etc etc are overwhelming evidence that such an entity does not exist. 

Epicurus: 

“Is God willing to prevent evil, but not able? Then he is not omnipotent.
Is he able, but not willing? Then he is malevolent.
Is he both able and willing? Then whence cometh evil?
Is he neither able nor willing? Then why call him God?”
