Isaac:
I've made the same point many times on this forum. Humans are not capable of determining that an entity is either all-knowing or all-powerful. We could make a rough determination that an entity appears to have super human powers but a determination of infinite quantities is just not possible. And we ought to question the motives of an entity that expects us to rely on our own finite powers to believe what the entity claims.
Add to this the Satan factor and you really make things complicated. Supposedly Satan is able to con us by transforming himself into what would appear to be a benevolent angel of light.
Even if this entity doesn't ask us to kill or harm someone it would really make me wonder if such an entity expected me to do an act of worship toward it. How pompous and conceited. Almost like taking advantage of a child. Do this you little helpless servile worm and then I will give you some goodies.
That's why I remain an atheist. God has yet to proposition me.
