They formed there. The sky is not really a thing in and of itself. It is simply what space above us. That space is enormous; far too large for the human mind to comprehend. The world we live on its just one planet in that space, which we share with the stars. The stars themselves are suns, some bigger and brighter than our own, but so distant that they appear as dim points of light. They formed from the collapse of enormous clouds of hydrogen an helium. As these clouds collapsed they heated up, eventually becoming hot enough to ignite nuclear fusion, a process that produces the light those stars emit.
