You’re trying to make an argument for solipsism, and against science

1. No, I don’t. I’d actually call myself a primitive realist.
2. Science and solipsism is not a dichotomy.

If you truly believed this, then you’d have no problem walking in front of an oncoming truck, as it may as well not be “real,”

Believed what? At what point in our conversation did I state my beliefs?

Instead, we can know the real world through testing and confirming material reality

Maybe stop spawning unnecessary entities? Here you say there’s real world and then there’s material reality. Wtf are those and what’s the difference between them? Are there other worlds? Are there other realities? Just stop for a second and try to comprehend what you’re writing.
