Since you're talking drugs. 
You probably get philosophical from time to time. 

So let me put it like this and you can let it pour over your brain and percolate all sorts of thoughts over the upcoming decades.

Rene Descarte said "I think therefore I am." 
So really I can prove I'm real. I'm experiencing me. You? Well you could be a Nostr bot. Nostr could not even exist. It could be a fed Honeypot and I'm taking to my NSA agent right now. You could be a different of my imagination and I'm schitzo. This could be the matrix and those octopus things implant you in the system so we're both real but what we experience isn't. 

I can't prove you're real or not🤷🏽 so why do I care about your opinion🤷🏽 why do you care if other people care? 

Not to be harsh. I still care about your opinion. But like really if you beat down to it. Why? Right? 

Furthermore, Carl Sagan once said we are all star stuff. Meaning we're made up of the same materials that the stars are all those lightyears away. Maybe literally the exact atoms from stars exploded eons ago. And if you think about it a certain way, it's like we are all a part of the universe as of it's one living organism constantly moving. Except in this view we are like the ants and fleas in our scale of the universe. So incredibly tiny that we couldn't really possibly have much impact in the long run whether it be out size in comparison to a planet or sun, how much importance we have in context of the gravity of a black hole, or the short length of our lives in terms of the start to the ultimate heat death of the universe. 

We are like the cancer cells on the universe's ass become conscious and slowly moving around leaving a path of decay. But in a lighter now if we are a part of the universe, as if it was a living conscious being of it's own, then really truly I believe the point of life is to live it. To experience it. And share your experience with others. 

Because if you do you. And I do me. Then we tell each other about it. That's how the universe learns about itself.
