You, may be right about it all, but can shadows exist without light? Can light exist without making shadows? I don't think so.
And I still got the feeling that SEGA is hiding something, perhaps we'll get a connection some time, and until then, there's always space for theories.
Also, I still believe that the Gurhal system, the system of PSU, is Algo, because of the many references. A very interesting one is in episode 2 of PSU's story: The headmaster says, that Moatoob once was a green planet, that was controlled by humans. Now it's a desert. Isn't that a pretty big reference? To me it sounds pretty much like Motavia (even the name), Motavia was once a green planet controlled by the Earthmen/Mother Brain, and after MB's destruction, it became a desert planet.
Also the names of all planets:
Motavia/Motabia/Mota: Moatoob
Dezolis/Dezoris/Dezo: Neudaiz (New Dezo perhaps)
Parma/Palma/Palm: Parum
But well, it's still just theory, probably we'll find out some time.
And it wasn't offensive meant or something, I don't wanna argue
