> The universe doesn't care.

And that's exactly why it's important.

> Survival of humanity isn't important universally.

Unless there is something there that cares about it, there is little reason for the universe to exist - nothing would know the difference.

Which is why it actually is important universally.

> But it's the most important thing for humans.

No, it's more important for the universe to have humans, than it is for humans to have a universe.

If the universe did not have humans (or another sentients) then it might as well not exist. AKA: Humans super important to the universe.

If humans did not have a universe, then humans would not exist. If humans did not exist then nothing is important to them.

That seems like a circular argument. It's not important for the universe to have a purpose, or to "care"...except to us. Things don't need a reason to exist.

What is the difference between a universe that doesn't exist, and one that no one notices exists? There is no difference.

The difference is itself: one universe exists, one doesn't. Notice doesn't define existence. Measurability doesn't define existence. Meaning doesn't define existence.

Why are you saying that the universe might not exist if it were not for humans. I have a few questions for you.

1. What if humans become extinct in a few hundred years? Should the universe then not exist anymore and make more lifeforms?

2. What if there are billions of other "intelligent" species in the universe? Why should the universe care about one specific species that is actually not that great, and very destructive.

3. What if this universe is just an experiment, a petridish and we are just one out of billions of parameters.

4. What if our kind of intelligence is really not that impressive, what if intelligence of dark matter entities, which we don't know about anything is much more powerful, what if even that is not that impressive?

Again, the universe doesn't care. It is not a person, it doesn't have a plan, it is neutral, unless we met our "gods" one day. Humans are just a blip among much larger things that are happening in the universe.

> Why are you saying that the universe might not exist if it were not for humans.

I didn't say that. I said there is no difference between a universe not existing, and one that has no one who notices that it exists.

Re: 1 and 2 I said "(or another sentients)".

3: I guess you are implying someone made the universe and is running it? In that case, they are the ones aware of it, so that counts.

4: Hu?? What are dark matter entities? We notice the universe and care that it exists. That's enough. The specific level of intelligence, (or aggression for that matter) does not matter.

> Again, the universe doesn't care.

That's the point. WE care, and we are the ones that give the universe a "voice" as you will. We speak for it, we do the "caring" for it. Without us (or other sentients) it might as well not not exist.

> Humans are just a blip among much larger things that are happening in the universe.

Just because someone is big doesn't make it important. Importance comes from meaning. A really big explosion in space, that does noting at all, is completely unimportant. While a tiny little seed that someone wanted to plant matters a lot.

I care and I am part of this universe, like you and every other human on this planet.

So at lest partially universe care about humanity.
