Distributed version control existed before git and performant distributed version control was created concurrently with the Mercurial project. Had git not been made it seems that Mercurial would have acheived the exact same thing. It's not clear what would have happened had Linux never existed, it seems that things could just have easily been worse, or better, and maybe even the same. It wasn't a particularly innovative idea to create a kernel capable of running GNU software using a copyleft license, and I imagine it would have happened eventually regardless, but it's not clear it neccessarily would have succeeded, or what the end result would have been.
