Well, they have a point. This is why the presence of liquid water on earth is a big deal.

But when the rocks start to melt you have problems.



Tungsten/Carbon based life forms? Solid when most everything else is liquid or gas.


It's very unlikely for life to arise under those conditions. To get life, you need to build a lot of random polymers in a short amount of time (relative to the age of the planet) and the only known way that can happen is in a liquid or a gas so you have diffusion working for you. But after that, to get technology, you need solids.

The good news is that you don't need to have the life arise under the same conditions that the technology exists. It's possible that the planet is inhabited by self-replicating tungsten-based technology that was created by life that arose somewhere completely different.

But the bad news is that we are much less likely to find the aliens than we are to find the descendants of the self-replicating robots they built millions of years ago. And the fact that we haven't found the robots makes it very likely that the aliens don't exist.
