To put it simply, water allows for certain interactions to occur. Without those interactions, life as we know it wouldn't exist. I am sure scientists have played around with trying to create life-like interactions with other molecule combinations, and those molecules simply don't allow for life-like interactions. There is no other atomic combination that we know of that provides the uniqueness that hydrogen, oxygen, nitrogen, and carbon have.

Maybe we are wrong and those unique traits can exist in other atomic combinations in completely different environments. The other thing to keep in mind is that we have limited resources, and most scientists would rather put those resources into what gives the best chance of success.

Do note that in articles like this "Earth-like" is used very loosely. We still cannot perceive much detail at these distances, so anything of vaguely Earth's size, in what we estimate to be a habitable zone for a given star, especially if we see spectra that indicate water, are going to be labeled "Earth-like". The planet could well be a sterile rock that bears very little resemblance to Earth.

As for water, it's is the basis of all known life and it's the singular most versatile solvent in a broad range of areas that make it unique. Water is so important to life as we know it that it's easy to conceive of life almost anywhere there is liquid water and almost impossible to conceive of how there could be life anywhere liquid water is absent.

Any life that doesn't use water is extremely speculative. That doesn't make it impossible, but it is hard to look for something we can only begin to guess at.

We can make assumptions about the planet, such as this one likely being tidally locked to it's star, however currently we do not know if it has an atmosphere.

If we do manage to obtain information about it's atmosphere we can make pretty accurate assumptions about surface temperatures, and another important point will be how active Proxima Centauri was in the past. There is a chance this planet spent much of it's early life being bombarded with radiation by it's star.

Love the mainstream media when they report scientific things like this they do not understand. The way they present this is like we found another green planet like ours with lush vegetation and creatures roaming around like it's No Man's Sky. Most probably this planet is completely deserted and dead. Earth like planet for scientists means it's a rocky planet in the habitable zone of its star and nothing more. They don't know a heck of things about this planet. It's too close to the the star to be mayhemed by solar flares or be tidally locked which means a dead planet again. They also do not know it's chemical composition and a series of other things. But the media do not care they want to present your average sci-fi story to easily impress.

With cynicism like that, no matter how realistic - you should go test the atmosphere yourself. Breathe it in.

If it brings it into the public eye and gets it more funding and interest I don't see it as a totally bad thing. People who are more interested than just reading a sensationalized article in passing will do more research on it anyway.

In our galaxy, there is an estimated 200 to 400 billion stars. If just 1% of those had at least 1 planet, and just 1% of those planets were capable of supporting life as we know it and just 1% of that life was an intelligent race, that still leaves 200,000 to 400,000 potential alien civilizations; or at the very least Earth-like planets where life could exist.

Extraterrestrial life must exist. I personally find the thought that our planet is the only one with life on it totally absurd. How? With so many galaxies and so many stars and the potential for so many life-bearing worlds, how can ours be unique?

Edit: What I said is pretty much a direct quote but I can't remember who said it... I think Neil deGrasse Tyson. Regardless of who said it, it's a remarkable idea that there could possibly be that many alien civilizations or habitable planets.
