It's true to a certain extent though. All you can know for sure is that your conscious self exists. Literally everything and any thing else could be a facsimile, an illusion...
For all you know you're just a Boltzman brain experiencing existence for the briefest moment before you decay to nothing.
But none of that really matters, we're the ones who give our lives meaning, so you might as well enjoy what you got while you still got it, whether it be chemicals or whatever the fuck.
Biology is complexity out of simplicity. Those mere chemical processes you deride involve enzymes, hormones, feedback mechanisms, homestasis, all working together. The simplest bacterium is more complex than any machine we ever made.
And enzymes, hormones and feedback mechanisms all are chemical compounds which react with each other. But even chemical compounds don't exist like this but are just another model based on abstraction.
Gonna perish like a dog anyway. It was going well until the neo-feudalist call to arms. Dogs are based, dogs didn't kill the planet.
The contrast in tone between the text response and Mickey's face is funny tho
Replication. If you take the same ingredients and put them together the same way you get the same thing. If you can repeat the process it's factual. This is a dumb philosophical argument.
