> There are so many unknowns that we can literally say nothing about it. Nothing. We have no idea. We have a sample size of one and virtually nothing to even calibrate any of the scales for any of the parameters in any model. You can't even prove to me that you exist. Yet we all seem to be able to agree on a lot of things. Re Fermi, we're pretty sure that gravity, physics, chemistry are the same throughout the universe. Biological forms did evolve on our planet, and our planet doesn't seem super-unusual. Given those things, we're pretty sure that there are planets with biological forms. Given that, I think we can say that there is a significant chance that other intelligent biological forms are out there somewhere. And then we get the Paradox.
