God is a metaphor for a being or group of beings that are most trusted. (I would say in many cases excessively trusted)

Then what is this being or group of beings? If god is a metaphor for them, then they are not god.

Only beings who communicate can be trusted.

Patently false. I have had great trust in dogs that were unable to communicate.

A non existent being cannot communicate.

Um. Okay.

We are taking about an entity of which there is no objective evidence. People think it exists and thin they communicate with it.

Your first point destroyed the proof all on it's own. if god is a metaphor the those entities are not god. Goes downhill from there.

Simply because the truth can change in time and place does not mean it is not the truth then and there.

How is it confused use that the Truth = objective reality?

Truth is that which is. If it is a matter of opinion then the word is meaningless.

There are three sides to any story. There is my side, your side and then there is the truth.
