Apart from being open source what is Linux? Could I not create my own operating system that is different to windows or Macos and call it Steve, again there might be an awnser for this and sounds stupid but its more out of curiosity.
You can 100% create your own kernel for an operating system, and call it Steve
Hypothetically, could a guy called Linus create his own kernel and name it after himself?
Sounds perfect… Just disappointed that Steve os has not been released :/ I can hope though!

But would it be in honor of Steve Jobs, Steve Ballmer, or Steve Seagal?
Linux is the kernel; that is, the core of the operating system, which handles memory, hardware, inputs… Every OS has one. Windows’ is called NT, macOS’ is called Darwin.
You don’t use the kernel, you use the OS. Linux is special because there several operating systems based on Linux; they are called distributions, and they are what you want to use.
You can create your own Linux distribution, by bundling various software packages with the kernel, in a way that caters to specific needs or follows a philosophy (for example, Linux Mint is a distribution focused on ease of use, Archlinux on minimalism…). This is not possible with Windows because their kernel is not licensed under terms which would allow this. It is with Darwin, but unusual.
You can also create your own kernel but this is extremely hard. Getting the computer to boot is easy enough (relatively speaking), but getting programs to run and things to display is much harder. Getting your custom kernel to a usable state is orders of magnitude harder, as it needs to work on and communicate with modern hardware and networks. Linux took more than 30 years of development by thousands of developers (some of them highly talented in a very narrow field of computing) to get to the level it’s at.
“Linux” has two meanings. One of them is the kernel itself; another is a collection of operating systems, that Stallman would call “GNU plus Linux” instead.
The later involves two factors. A “hard” one is the presence of the Linux kernel; but there’s also two softer and fuzzier ones:
- the operating system behaves like other OSes that the user calls “Linux”. For example you’re expected to have a /home/username, you can install a different DE/WM if you want, this kind of stuff.
- the OS is open in letter and in spirit. This is ideological but ideology is damn important when dealing with Linux.
A good example of both is ChromeOS: people don’t usually call it “Linux”, even if it uses the Linux kernel. It’s simply too atypical in behaviour, and ideologically too distant from the open source movement.
Just a little addition: the majority of things that people associate with Linux as per your first item are actually shared by many/most Unix-like OS and are defined via the various POSIX standards.
That’s not to say that Linux doesn’t have it’s own peculiarities, but they are fewer than many people think.
They do - and in some cases you can fit both items to a T, without fitting the “hard” requirement (Linux kernel); that was the case with Debian/kFreeBSD for example. (And even “vanilla” *BSDs feel right at home for most Linux users, I think.)
I’d just like to interject for a moment. What you’re refering to as Linux, is in fact, GNU/Linux, or as I’ve recently taken to calling it, GNU plus Linux. Linux is not an operating system unto itself, but rather another free component of a fully functioning GNU system made useful by the GNU corelibs, shell utilities and vital system components comprising a full OS as defined by POSIX.
Many computer users run a modified version of the GNU system every day, without realizing it. Through a peculiar turn of events, the version of GNU which is widely used today is often called Linux, and many of its users are not aware that it is basically the GNU system, developed by the GNU Project.
There really is a Linux, and these people are using it, but it is just a part of the system they use. Linux is the kernel: the program in the system that allocates the machine’s resources to the other programs that you run. The kernel is an essential part of an operating system, but useless by itself; it can only function in the context of a complete operating system. Linux is normally used in combination with the GNU operating system: the whole system is basically GNU with Linux added, or GNU/Linux. All the so-called Linux distributions are really distributions of GNU/Linux!
Just in case OP doesn’t know, this whole text comes from someone else. Some people prefer using words other than GNU/Linux.

That’s a Stallman rant/copypasta. Calling it GNU/Linux isn’t very common outside of his fans.
It’s also wrong, There are Linux distributions that don’t use the GNU userland such as Alpine which uses musl IIRC.
