The reason for the convention is that it used to be just a pointer (adress) to consecutive elements in memory. A[x] is then literally translated to the adress of A + sizeof(x)*x. Meaning that the first element is at A[0].
I mean, it's still the case under the hood, and languages like C do work that way. Sure, it's abstracted away in most programming languages these days, but if you ever need to do direct memory management, it's very much still how it works.
