I think people might end up disappointed with Eywa in the future;
As the plot unfolds, we learn a bit more about Kiri and her conception, but the main question remains unanswered: why did Eywa create Kiri? What is her purpose?
And considering that Avatar 4 will be narrated by Kiri, perhaps we’ll finally unravel this. However, I also think there’s a real chance fans could be let down by Eywa.
It’s not uncommon for people to wonder why Eywa didn’t help the Mangkwan, why she seems to favor humans/avatars over the natives, or why she only intervenes when called upon. While these questions are valid in theory, I think we’re overlooking the main point:
Eywa isn't just a deity the na'vi believe in and connect with; she is the entire living planet. A planet can undergo natural disasters and face its own internal issues, but that is completely different from being constantly attacked and destroyed by an external force (humans/not natives)
In interviews, James Cameron has practically confirmed that Eywa can only "see" everything through her roots; if those roots are destroyed, how could she know what’s happening? That’s why she only "strikes back" when someone alerts her.
Finally, there’s the matter of religion. JC clearly draws inspiration from diverse, non-traditional religions for Eywa, yet he also weaves in subtle biblical elements throughout the film. My point is this: we shouldn't try to fit Eywa into our own religious frameworks; doing so will only lead to disappointment and more questions.
James Cameron never promised that Eywa would be omnipotent or anything of the sort, nor did he ever say there is a concept of heaven and hell for the na'vi—so we shouldn't be questioning her through those lenses. But I think sometimes people can miss that point and get carried away; I've actually seen some fans hating on Eywa with all their hearts after the Mangkwan were introduced.
I'm not saying we can't theorize or anything like that too, but sometimes we can create expectations based too much on our experiences and forget the true message or vision.
