How do I form a sentence of these patterns "X does not arise from Y", "X not due to Y", "X not because of Y", "There are other reasons for X". Since obviously I cannot simply slap ない onto から or ので to form an "anti-causal" particle.
Would the below constructions work?:
Are there better options for this type of relationship between X and Y? Or do more colloquial forms or set phrases exist for stating anti/non-cause? I'm not sure if my constructions sound unnatural. The way I constructed those statements feel quite literal to me.
