Extraterrestrial life might be less common than thought previously?
There are a lot of calculations based on statistics that there should be a lot of life in the universe.
One example for this is the Drake equation.

Scientists met in Cardiff (United Kingdom) and came to the conclusion life in the universe might be rare.
The team around Jane Greaves and Phil Cigan from Cardiff University stated that the for life necessary phosphorus is very rare in the universe. It originates from supernovae in small quantities and spreads in all directions from the explosion. The team stated this on the EWASS 2018.
EWASS stands for European Week of Astronomy and Space Science.
Why do they think phosphorus is a key element for life?
Dr Jane Greaves, from Cardiff University’s School of Physics and Astronomy, said:
“Phosphorus is crucial to the compound adenosine triphosphate (ATP), which cells use to store and transfer energy. Astronomers have just started to pay attention to the cosmic origins of phosphorus and found quite a few surprises. In particular, it is created in supernovae – the explosions of massive stars – but the amounts seen so far don't match our computer models.”
My first question here would be: "Couldn't there be circumstances where it is not necessary to store energy or couldn't there be a substitute for phosphorus?"
But who am I to question scientists ;)?

What do you think?
Is a lot of phosphorus really necessary for life?
Could it perhaps be substituted?
I think that many scientists are too narrow-minded. If this is like it is, then that can't be or must be ...
As you can see in my "about" at the top of the page I like to look at things from another perspective.

I find it very hard to believe that we would be the only ones in all of space. We can't even think to travel far enough to see what is out there and it's just so vast how is it possible that our spec of dust (in the realm of space) is the only spec that can have life and still does.
Completely agree that scientists are to rigid many times in their thinking. They have a hypothesis and go out to prove it. This approach leads to finding facts that support their thoughts while ignoring others that may have much more importance if they just went into things with a completely open mind.
I totally agree with what you say @thedarkhorse.
In my opinion, many scientists have an opinion and try to prove it's correct.
When I have an opinion/idea about something my first thought is why I might be wrong about it and why it could be different than I assume :)
Maybe I'm a bit strange ...
Not strange, just open minded and willing to accept that you aren't always right.
Honestly this is the exact same problem with the "News" also. They are trying to prove their agenda vs actually reporting the news which should be done in an unbiased way.
Governments are the same too. Look at the whole Syria situation right now. IMO there is no way to know if the information we are being fed is real or fabricated to support the working position of Governments that are controlling the information.
It happens at so many levels and that means all information we take in needs to be looked at with a critical eye.
WOW - finally found somebody again thinking the same way as I am!
There are more and more critical people around but most people still think "It was on the news on the telly - so it's true" ... so sad.
Many people are manipulated by the well paid MSM on daily bases and questioning what they are told.
And when asking them they will deny believing but still spread the "news".
The phrase sheeple is very fitting for a lot of people.

It's absolutely how absurd how human mammals are so vain to think that humans define everything or it doesn't exist. I get into stupid arguments over this. I have indigenous polynesian blood, in the ancient lores all has life essence which is conscious information field— even a lettuce plant for example. Now science says, "Whoa, discovery! Lettuce can hear you eating it!" Duh! But don't tell the hardcore animals activists (I am one, just not hardcore) that plants are alive too. How we define life is all to coddle justifications with how we are and what we do, and being the center of our universe. I absolutely believe — even from a purely statistical standpoint — that life exists without carbon or phosphorus or anything we care to define because I define life as awareness of itself — even chemically and reactively.
It's also probable that others exist simultaneously at present, but we experience only the limited amount of existence our brains and tools allow us to data process. Even our tools are build to select data with bias in favor of what we can process. If we don't experience it personally, we consider it null. Foolishness.
That indeed is quite a statement which I can support.
Actually, I doubt that we can give a 100% correct definition of what is life / alive.
We know that in a healthy wood trees support each other.
Are these trees alive or is it just an ecosystem that looks like being alive?
We are simply to stupid to tell for sure ...
I'm bummed I didn't see this reply. And I ask the same questions but I favor on the side of assuming life until proven otherwise. And what is life? Yes, it gets philosophical because if a mushroom isn't alive then are we? All I know for certain is how my own brain imagines reality to be. We all share some common ideas about what reality is because we're all working with similar hardware (brains) as macro-organisms. How do we know that the yeast in our stomachs aren't daydreaming they're the center of the universe and we don't exist to them. Lol.
Anyway! Definitely we have to wait to see how many matches are used to reach a conclusion ..
