Lots of assumption.

The most we can say is intelligence emerged from the increasing complexity of biology, improving survivability for the animal, enabling it to outlive other animals without intelligence.

Anything beyond that is supposition.

This may sound harsh, but it’s a “you” problem. Other people aren’t reacting the way you expect them to, and you’re disappointed.

We don’t get to choose how others behave. Having an expectation of such things is a clear path to disappointment.

I’m not Buddhist (I’ve read a little), but it seems to me this is a fundamental understanding in Buddhism, isn’t it? It’s certainly something I’ve seen in Eastern thinking/philosophy, and embraced in Cognitive Behavioural Psychology.

What relevance does that have to you learning a religion?

Just go learn, there’s a million reasons someone would want to go learn. No need to add anything that can add confusion.
