2. While a very cool discovery for sure...

Here is a partial list off the top of my head of why there are so vanishingly small opportunities for us to contact or discover life on other worlds...it almost undoubtedly exists, but it is also almost assuredly out of the grasp or potential for us to contact it...

1) Distance to Star / Orbit - this one seems to be OK for K2-18b...
2) Star's Radiation Intensity - this sounds a bit more sketch for K2-18b...
3) Planet's Magnetic Fields (to allow for protection from complete planetary irradiation and sterility)...sounds like an unknown for sure...

Then there's a bunch more concerns too for intelligent life to develop...

- the ability to access the water (if it is vapor, that may indicate a surface temperature too high for conventional life, but possible for extremophiles)...
- the life's ability to coordinate something akin to opposable thumbs and brain capacity increase along the lines of homo sapiens and the hominidae line in general's success...
- the presence (or absence) of a large planet to deflect or absorb meteors, asteroids and comets the way Jupiter protects the Earth from more frequent, and more catastrophic impacts...
- the lack of a suicide society such as has grown up on Earth - where the survival of the species and protection of the environment are shortsightedly sacrificed for temporal gains and transient things like "wealth" and "privilege"...

The chances of ever meeting "E.T." are about as likely as TRump dropping dead of a massive stroke this very second....damn, just checked and he did not acquiesce (yet?)!!
