>If this was the case, wouldn't we all be duped into worshiping the devil or an evil alien by now??
Of course you can dupe yourself into following some false deity, this is what false/partial ET disclosure was aiming for. If you have a good positive intuition you will KNOW right from wrong.
> why are things allowed like God and light
Because Free Will is respected above all. Positive ET's know and respect this, and make sure this is so.
