I wouldn't put too much emphasis on the "I can't prove they aren't" part. Having taken a few philosophy classes in college, I quickly realized that you can't actually prove that solipsism is wrong. I can't actually prove that everything I see, every person I talk to, isn't just a figment of my imagination. And yet, I categorically reject solipsism anyway, as any sane person should. The world is real, other people are real conscious beings, and so on. To believe otherwise is to literally be insane. And yet, any argument you could come up with for rejecting solipsism, a solipsist would reject: "Oh, that's just a figment of my imagination going off on a tangent again."
Just because you can't prove an assertion doesn't mean it's wrong.
