That's all really nice and all but it is contradicted by the movie itself. Vejur did not create a divine being in its mind...
Vejur's Creator, the living machine it expected to find on Earth, is compared numerous times throughout the movie to a deity/God/divine being.
"Capture God? Vejur's in for one hell of a disappointment."
"A father... a brother... A God... and asks... is this all that I am?"
"We all create God in our own image."
The way the movie is written, the Creator is depicted as Vejur's God. It has all the answers. The message couldn't be anymore obvious if it was delivered with a marching band.
... but it had imagined what it believed its Creator was. Vejur didn't create its Creator.
Vejur had a false image of who and what its Creator was. A machine that creates machines, gives them a purpose, answers questions, all by intention, all by design.
That ultimately false and self-inspired image was created entirely by Vejur, and discarded when new verifiable information became available.
It knew it had a creator when the Ilia probe was answering why Vejur was traveling to the third planet ahead. Because that is where the creator was and Vejur knew it to be true due to data it had that confirmed it.
When Vejur made the decision to return to the third planet, it was following its primitive NASA programming, which instructed it to "... learn all that is learnable. Return that information to its creator." At that point, it was merely returning to the point of origin to complete an instruction.
Somewhere along the line, it became alive, and wanted more than to follow simple instructions. It wanted answers. Then, creator became Creator. No longer the mere point of origin, but the source of its very existance, and the answers that it sought. With that, Vejur
guessed that its Creator would be like it, making the Creator in its own image.
Of course, it guessed wrong, and wasn't blessed with humankind's stubborn refusal to let go of myths... after joining with its
real creators, human beings, it gained something far more valuable... freedom of thought.
Vejur never found its Creator. The Creator, a superior living machine, was a figment of its imagination, based on guesswork and assumption. Because it let go of this error, it found another answer, the
real answer, in the same place. Motivated also by the Ilia/Vejur attraction to Decker, it joins with a human. Like humans, it can now answer its own questions without the need for a cosmic voice to guide it... "I think we gave it the ability to create its own sense of purpose... from our own human weaknesses..."
The promise of finding its Creator, another living machine, was a good motivation to get its ass moving, but it ultimately found its true answers elsewhere: within its new-found imperfect humanity. Just as well it let go of its living machine expectation, too... or, as I said before, it would have digitised and wiped its answers out of existence based on a false assumption.
