It makes sense because it's de facto standard, and intuition is experience, and intuitive is what we're used to. I'm not sure how it can be explained more basically.
That's not an argument that scales well, as then we'd have a single programming language, anything else being un-intuitive. Every single non-obscure language that exists today had to go against the (previously acquired) intuition, introduce new concepts and then work its way up to the point where new concepts are the (newly acquired) intuition.
