Was Religion more specifically Christianity created just for humans? Do you believe other animals are capable of learning theological morals?

The point of this question is not to bash Christianity or to bash religion all together, it is simply thoughts. I am on not on a specific side I simply want your opinion and my goal is to be eduacated if my questions come off as ignorant. Earlier this week in my college class Earth History we spoke of how significantly small humans, other animals, and our Solar System is compared to our entire universe. It made me think about Christianity specifically the Bible and how it has focused primarily on human morality and our relationship with God, disregarding behavior and morality of other animals. Also, think about what God has created all of the magnificent creations as in planets and galaxies, something’s we still can’t even comprehend. Are we truly Gods greatest creation? We have seen that other animals in our own planet have potential and capabilities. Yet we are the focus. The thought of humans not being the center of universe being that we are so small compared to the rest of Gods creations but yet most religion is revolved around humans. When we think about the morality of other animals we tend to not think they have morals at all, that all of their behavior is instinctive. When I actually see people and scientists teaching morals to dogs and chimps. As in how to properly behave in public or how to tone down aggressiveness for the sake of other people and animals. Should animals play a larger role in religion? Should the talk of other planets and space have a larger role in religion? All of these questions I am left with right now that I’ll eventually find a solution for, I’d just like some input.
