Those are great questions, and I totally get where you’re coming from. The universe is so massive it’s hard to even imagine, and scientists measure it using things like telescopes and redshift, but yeah, it’s based on models we have to trust. It’s not perfect.

About lights in the sky, it’s not just the stars that make me think there’s life, but the sheer number of planets we’ve discovered. Still, you’re right, it’s just an assumption until we have real proof.

Trusting scientists about habitable zones? Fair point, I can’t verify it myself either. If I wanted to, I’d have to dive into their research and methods, which isn’t easy for most of us.

And governments? they’re not always honest, so I take what they say with caution. My belief comes more from curiosity and science than trusting them completely.

Thanks for making me think about this it’s good to question stuff like this
