Not necessarily life itself, but astrobiologists also look for biosignatures, or components of life as we know it.NASA deals in probabilitiesExactly what an alien assuming human form would say.....
‘There’s a Chance’ of Alien Life Out There, But it Hasn’t Visited Earth.
Nobody in NASA has a clue if there is life outside Earth.
None of the scientists have any more valid information on that than any other human because right now we only have one data point and that is earth.
Until we get another data point from some place else all we have are jackshit guesses.
They look at the vastness of the universe and calculate the probability of the existence of life.
Then they look at the vastness of the universe and calculate the improbability of ever getting there
Agree. Science deals frequently with inferences, inductive logic, and “concludes” with probabilities that a hypothesis may be true, or not.
Replication of methods & data are important to increase certainty.
In the case of intelligent “aliens”, there is nothing to replicate, only inference.
Correct. In order to do any valid probability assumption you need a data population with more than one data point. Until we find life elsewhere no probability projection is valid. It doesn't make any difference if a NASA rocket scientist is making the assumption or not.
The problem with people making a statistical inference that we are not alone in this universe is that they have been brainwashed by Science Fiction. Everybody just knows that there must be other life in the universe because they have seen it so many times in movies and on TV and read it in books. However, Science doesn't support it until we learn more like finding life elsewhere.
I am any engineer and not exactly ignorant of science and while not a astrobiologist or astronomer I don't have a clue what a celestial "biosignature" would be. Carbon? Carbon is a building block of life as we know it but by itself isn't life. If it was then the charcoal in the bottom of my Big Green Egg would be alive.
Water and carbon doesn't produce life. If it did then every Jr High Science class would be creating life as a lab assignment.
Lets get another data point and then we can talk.
