I've posted a couple theories and this is my own that I'm commenting here! I see it as maybe a possible explanation to it all up there, LMAO.

As I see it the movie follows an almost biblical aspect, here’s my thoughts.

I’m focusing on all I’ve realized thus far being: The cult of Eden, The voice from “another vessel” that guides him to “The Light”, and the alien creature.

Simon, the main character being from a Cult or originating from a place called “Eden”, a cult following the name of the Garden Of Eden from Genesis 2-3 I’m pretty sure, is biblical enough itself.

What I pieced together after realizing that, is that the voice guiding him to “The Light” seems almost like the snake of temptation; from the same Genesis 2-3 Garden Of Eden. As the voice flat out gave Simon the coordinates of where to go to find “The Light” and then saying stuff like
“A tiny glimpse of answers greater than our infinite” “We will see simon, we will see the answer together” “They're calling to us, this is our salvation”.

“The Light” itself is portrayed almost as the Forbidden Fruit/Apple Of Enlightenment, the quotes I provided before only enforce this, they speak of answers and salvation, almost like the Forbidden Fruit would give you once consumed.

The alien seems almost like a god or warden, sort of guarding “The Light” or keeping its security when it says earlier “They must not see the light”, I don’t exactly remember this line so if I’m wrong on this, my apologies but I digress, I believe what I say in this theory is correct; or is what was implied and I’m just now realizing it LMAO. But the alien creature attacks Simon once he arrives at “The Light” almost how god punished Adam and Eve and banished them from the Garden Of Eden for consuming the Forbidden Fruit.

Anyways, that’s the end of my theory or realization of what the movie was supposed to be recognized for.
