Now you are just trying to be clever with words to wriggle your way out of your logical quagmire. Your premise P1 requires a proof of a negative (that logic, truth, and knowledge cannot exist without the God of the Bible). But anyway:
P1 Inanna is the necessary precondition for laws of logic, truth, and knowledge (by the impossibility of the contrary)
P2 Laws of logic, truth, and knowledge exist
C Inanna exists
Thus, it is the Sumerian god Inanna (who, among other things, made decrees referring to lordship, wisdom, understanding, victory, judgment, and decisions) that exists.
Again, you’re just trying to be clever with words and start a pissing contest. The burden of proof lies with the one who makes the claim. You claimed that “The God of the Bible is the necessary precondition for laws of logic, truth, and knowledge (by the impossibility of the contrary)”. You offered no proof or evidence supporting it (you just stated it as true). The burden of proof was not met, so your assertion is is unfounded. Thus, I need not argue any further to dismiss it.
But hey, show us some objective empirical evidence that supports your claim P1, and we can discuss it further. Until then: meh.
I noticed that you provided no competing account for the laws of logic or truth and knowledge.
I do not need to. Because you made an unevidenced assertion. I need not disprove your unevidenced assertion. You need to bring forth objective empirical evidence that supports your assertion. Until you do: meh.
Surely you can see that the absence of any competing justification only serves to support the claim that they cannot be accounted for apart from the God of the Bible, no?
I do not need to provide an alternative hypothesis to dismiss your claim as unevidenced crap that can be tossed right into the garbage bin. If I claim that Glargnorg the Infinite Brain Infector is the one who plants the falsehoods of the God and Jesus myths in your brain, it is up to me to show evidence for it. If I don’t, you are free to dismiss it without any further evidence, and you don’t need to offer any alternative explanations. Easy peasy.
