Some will say, well if the acausal is a 'cause' from negative existence, then wouldn't that be the first cause? Wouldn't that be God?
The answer is yes and no. While technically it could be considered as first cause, it is not any type of entity per se. It's more an abstract function of the negative aspect of eternity. God would be the positive aspect of eternity.
Now if God were able to 'not exist' and at the same time initiate its' existence then this would of course create a paradox, and at this level of reasoning paradoxes can be acceptable while also somewhat a slippery slope.
Also, God functioning via negative existence leads right back to the problem of infinite regression where time would be required in order any action to be performed which invalidates the negative aspect.
Infinite regression is akin the mother of all paradoxes, and should be avoided in my opinion. In the absence of any beginning time hopelessly regresses without there ever being a point from which to proceed forward, and while eternity may function in this manner, time does not.
I do make use of Occams' Razor where I can, but to do so here, would eliminate what appears to be a very mysterious as well as crucial piece of the puzzle, and I prefer my puzzles without any pieces missing.
