Thousands of scientific journals exist and new ones get created on a regular basis even by dissident scientists who want to publish their own research, however crazy it might be (there is notably long-running one even for cold fusion topics, I'm aware several exist for parapsychology, etc), but they don't have the "Impact Factor" of Nature, so almost nobody cites or even reads the papers they feature.
