Theres only one problem. For something to create the material universe, you would think it would have to be pretty smart, right?

I mean to actually think of all the physical rules and organize everything, it would have to be a really high IQ.

Now we as humans, would not be able to understand the reasons why it does what it does. Or whether its actually evil or good.

Its like a mouse in a research lab. The mouse is being used by us for a reason. To the mouse, we are evil because of what we are doing to it. But to us we are not evil, because it needs to be done to save lives. There is no way the mouse would come to that conclusion, even if it was directly told by us. To the mouse our IQ is superior beyond comparison.

So this demiurge, who knows what its intentions, reasons, or beliefs are because its IQ would be beyond our comparison. We are not at its level, therefore we cannot understand or comprehend it, even if it told us.

And just like people use animals for its own gain, I'm sure this demiurge uses humans for its own gain too. People are nice to their pets and love and care for them, but to their food they really do not care about. So I'm sure there are humans on earth that are the "pets" and others that are the "food".
