It is absurd.
About as absurd as that celestial teapot. There is no reason to suggest it, and no evidence for it. Given what we know of teapots, there is no way one could be in distant space. And given what we know of ideas, there is no way that some of them could materialise somewhere independently of the mind that thought them up. Although if you really do want to admit the possibility of the latter, it opens up all kinds of religious possibilities that I won't go into.
