habitable planets

[CapnAwesome]

Considering that people died from being exposed to new continents,  I'm skeptical that there is a habitable planet. We evolved for this one.

Yes, but those new continents are still habitable.

There is a great range between “some people with great effort can live on it” one the one hand, and “not even the unprepared is likely to die on it” on the other.

You think of the estimated >400 billion planets in the Milky Way, not one will have conditions falling in that gap?

We can't really know, now can we? I guess if humans develop the technology to reach them, they'll probably have the technology to survive on them.

However if diseases here on earth can wipe us out with such success, that other worldly ones would have a 100% kill rate, as we would have 0 immunity. Of course anything about habitable worlds is just 100% speculation. We have 0 idea about how common life is in the universe.
