How can they determine what molecules are on a planet 120 light years away?
Roughly speaking when molecules are hit by light they are energized and emit light at certain frequencies that are essentially fingerprints.
When that light reaches us here on earth we can analyze it to see those fingerprints and ID the molecules.

That’s not evident at all.
In fact it’s a paradox.

Yeah
And we’ve never found life. How much we look doesn’t change the fact we have found any yet.

So we can analyze the atmosphere of a planet 120-light years away but we cannot cure the common hangover…
One giant headache for mankind!

It’s terrifying to think what an alien creature looks like that lives on a planet with 8.6X more gravity. Shorter and drastically stronger with super dense skeletons.

When though? Of the roughly 14 billion years of the universe we’ve been searching for ET for 65 years.

There are 100,000,000,000 stars in our galaxy alone. There are millions of other galaxies. It would be insane to think there are not thousands if not millions of planets out there with life.
The problem is that the closest star to us would take 70,000 years to get to with our current technology.

How much for some exoplanet sashimi?

. A repeated analysis of the exoplanet’s atmosphere suggests an abundance of a molecule that on Earth has only one known source: living organisms such as marine algae.

Dimethyl sulfide, dimethyl disulfide, and dimethyl trisulfide have been found among the volatiles given off by the fly-attracting plant known as dead-horse arum (Helicodiceros muscivorus). Those compounds are components of an odor like rotting meat
Wiki tells me that the planet must smell really bad! Also tells me that chemical can be made 100% abiotically in the lab.
A cynic might suggest that NASA wants a budget boost rather than cuts.

many of the same folks in the scientific world (and society in general) who would quickly call evidence of a protein or amino acid or other things lesser than a cell on another planet “life” are the same people who argue against a multi-billion cell human fetus at the end of gestation as not being “life”…how peculiar
This is disingenuous.
There is "life" and "human life". A sperm is alive, no one rational is arguing that is a human.

It's called spectroscopy and is similar to how GC-MS works in a chemistry lab. Electrons in an element absorb photons in a certain way and reveal the fingerprint of that element or compound. The telescope can see it.
James Webb isn't powerful enough to see planets the size of earth, so they are looking at planets in the "super Earth" (or larger) range. If we could look at planets the size of earth, no telling what would be found.

Don’t let a disagreement like that distort your picture of the whole existence of the Church and its immeasurable contributions to modern society.
Basically all of the science that we have today that has allowed for so many modern marvels was preserved and advanced by the Catholic Church. Most of it would have been lost amid the chaos of the Middle Ages if the Church had not kept it alive.
There was a great deal of chaos and unrest in Europe when antiquity ended because of the power void caused by the collapse of the Western Roman Empire.

How exactly do you suppose algae on another planet effects Catholicism?
The idea is that if there is life on other planets then Christianity is debunked because somehow God can't possible have created life on different planets with different rules or have different salvation plans for different higher lifeforms. It's a simplistic argument that has no merit.
With that aside, this is an incredible find and I hope it's true.

Your argument is disingenuous. No one is arguing that a sperm is a human being. Billions of them are produced and die in your testicles every day.
However, a fetus is undeniably a living, growing human being, and biology confirms that. He/she will continue to grow unless killed by natural causes or by the intervention of adults who don’t want the child.
