Why is NSLog called like a C method rather than an Obj-C method?

So NSLog is a method that writes to the console. But when we call it, we say

NSLog(@"Blah Blah Blah");

rather than

[NSLog @"Blah Blah Blah"];

Any reason behind this? Or is the second way possible to do? The question is kinda stupid, but it's really bugging me as to why we do it this way...

We call it like a C function because it is a C function, not a method. A method is tied to a specific class, where NSLog is not

Oh okay... So not part of any Object means call it like a function. Got it!
