But there are a lot of similarities, are there not?
Similarity does not prove connection. Similarity is frequently the result of coincidence or parallel evolution. The eye evolved eight separate times in the history of life on Earth. All the different types of eye are similar because they evolved to fulfill similar needs and were shaped by the same laws of physics, but they evolved entirely independently of each other.
Then there's the common tendency to assume that if two works of fiction are similar, then one must be a "ripoff" of the other, when the reality is that accidental similarities happen all the time and it's hard for writers to avoid them. When I sent my first spec script off to TNG, they aired an episode with a similar premise the very next week, rendering all my work for naught. When I later pitched for VGR, it turned out that one of my pitches was similar to a movie script the producer I pitched to had written.
So similarity proves nothing but similarity. It's a big universe, and any viable pattern is bound to recur.
Semantics, IMO. Stars and Space could be seen as interchangeable to some species. There are stars in universe A, stars in universe B, and Fluidic space exists "between the stars".
And you accuse me of playing semantics? That's one of the most absurdly labored justifications I've ever heard, and it's completely unviable. The line about "the wastes between the stars" was spoken by Tam Elbrun before he'd even met Gomtuu, before he'd had any telepathic contact with it. It's in the scene where he first describes what the Starfleet probe detected and why he's been assigned to try to communicate with it. http://www.chakoteya.net/NextGen/168.htm So it is absolutely impossible that he could have any specific knowledge of Gomtuu's origins when he says those words.
