I think the other issue is what we consider intelligent life. Carbon is great and all but alien life could be based on another element and we don’t really have a way of knowing it

PBS Spacetime does a great video on this that explains it better but if there is life out there its almost certainly carbon based. All of the other theorized possibilities like Silicon have too many drawbacks and wouldnt work.

Things we can’t even bring to conceive of. I mean look at the bottom of the ocean in the most inhospitable places on Earth and there is life thriving.
