I mean a mechanism for why life should start.
It does at least set out what it is that we need to determine, to be able to work out the probability of life elsewhere. As the years (and centuries) roll by, we'll tick off the variables, bit by bit
Sorry if it came out that way, but I also work in marketing
aside from full time sales.
"why"? In what sense?
Let's take mountains as an example, to make it extra clear.
We know of geological mechanisms that results in mountains. Plate tectonics, vulcanism, etc.
Where's the "why" in this process?
I appreciate that we have plenty of work to do! But I don't think any of those constants are beyond us, from where we're sitting. Accurate assessments of them may always be difficult, but for the Drake equation to start working, we just need an idea of the size of the numbersEven that might be a bit doubtful. I can't think of any other equation in physics, which is just a string of constants multiplied together.

We don't need to know if the probability is 1 in 1 billion, or 1 in 10 billion. We need to know if it's 1 in 1 million or 1 in 1 trillion. Rounding is fine for our purposes. We just need to know the exponents, and we can begin to at least estimate them as we get better at analysing other star systems.I don't need any accuracy.
Just plug in some random numbers, and give us a best case scenario.
What pie-in-the-sky combination would "push" life into existence?
What is the point of making an estimate when there is, as yet, insufficient grounds for assigning a meaningful number to at least one of the factors?I don't need any accuracy.

No. the Drake equation is not a model. The Drake equation is a meeting agenda. When the young Frank Drake convened a meeting on the possibility of intelligent life elsewhere in the universe, back in1961 at Green Bank observatory, he needed something to give structure to the meeting. The famous equation was the result.They call them theories or models.
It's quite common.

The famous equation was the result. It has since been usurped by a multitude of researchers, science popularizers and commentators to push their individual views on how common or rare, intelligent civilizations are. Possibly, when all the terms are well defined - certainly much better than at present - we can begin to treat it as descriptive model. We are not there yet.
There is no probability. Create a model that suggests why life would form.
What factors are pushing rock to become life? What forces are at play?
Hmmm.
The questions you linked, all refer to the mechanisms of how mountains form.
While the "why" you used in the life questions, seems to be more like a "why" in the sense of purpose or intention. This "why" implies agency, while the "why" of the mountains only refers to a mechanism or process.
Can you explicitly confirm if you mean "why" in the sense of purpose/intention, or "why" in the sense of mechanism / process?
You also confused me with that first question a couple posts back:
"I mean a mechanism for why life should start"
You don't seem to be asking about a mechanism or purpose. You seem to be asking for a reason. A purpose or intention.
Is it not possible that it was nothing more than a series of chemical reactions (however improbable it may seem without knowing the conditions)? We know organic compounds can occur naturally, even in space.
You asked me to clarify. I did exactly that on your chosen topics.

Even if all of the right variables had allowed for a perfect, inhabitable planet, why would life form?
The second important question of General Biology: “How and why would life form in the universe?”
What is the scientific reason life exists, or what scientific laws have "pushed" life into existence, on this one planet?
Scientifically speaking, What is the Purpose of Life?
Why would life form from non-living matter?
For what reason might it form?
It seems to have infinite complexity and amazing adaptability.
What is pushing for that to happen?
Why does it fight against all efforts to kill it?
What is motivating life to keep on, keeping on?
Sure. Which ones point to life?
Do you have enough results
to work with? Do we need to
dig up all of Mars to find more
data points?
I agree, we need to get to work, I expect and hope one day we'll have the answers.
But, as I've said, your clarification wasn't clear.
Which is why I asked to be explicit. Which you didn't do, for some reason.
