I think you're inaccurately conflating individual purpose with universal significance. The discussion of purpose has nothing to do with our geocentric position when it comes to the cosmos. I don't think none of us here are saying the universe is alive why you and the other guy keep bringing up sentience when nobody here said the universe is aware.
I wouldn't even go as far as to say we know the universe is or isn't alive. As you said we are small in the universe so it would be arrogant on your part as a miniscule life form to assume the universe lacks sentience. We don't know but that is not the topic of discussion.
As I said before I feel my purpose is to help people. I'm good at it, I'm able to connect with people in my profession so I would say therefore that is my calling and purpose. Someone else who is good at sports may think their purpose is to be an athlete.
As I've said we all define our lives differently based on our experiences.
My first post on this thread read
"There is no purpose to life. Just ask the universe and listen closely to the answer.
There are personal goals, that's a whole different game."
There are personal goals, that's a whole different game."
Life itself has no purpose. Sure there are philosophical views, there are religious views, there are egocentric views, they are simply personal opinion. People are welcome to their views but consider, no one has ever provided a purpose for life in general other than to procreate. Call that a purpose if you want, it still boils down to a personal goal.
As i have mentioned several times. The speed of light and the huge scale of the universe prevents any form of grand scale sentence. As i have also said before, piezoelectric material can produce electricity which may evolve sentience. That can only be small scale as in inhabited planets.
As i said, people gave personal goals, there is no argument with that, helping people is a purpose to your life, not life in general.
