There is of course the very old argument that we are alone in the universe. It is the belief that humans are at the center of the universe and everything orbits around us. We are the center of everything and nothing else resembling intelligent life could possibly exist elsewhere.
Yes, that could be a takeaway from the current exoplanet reports. The belief stated however, was held for centuries in astronomy going back to Claudis Ptolemy. There were very good observations used in the geocentric solar system model to argue their position. It took rigorous observation and testing to change that model in science, thus the heliocentric solar system is confirmed with *heliocentric certainty*
I note in the space.com article Trappist-1 e exoplanet is held up as potentially, a very habitable world where life may exist. "Excitingly, one of these planets, TRAPPIST-1e, orbits its parent star in the habitable zone, the region with the right temperatures to allow for the existence of liquid water, a key ingredient for life. As Webb intensely studies the atmosphere of TRAPPIST-1e, often described as the most "potentially habitable" exoplanet ever discovered, it will look for molecules that could have been produced by life."
Unlike the heliocentric solar system and many observations supporting, nothing here at the moment. http://research.iac.es/proyecto/exoatmospheres/view.php?name=TRAPPIST-1 e
This exoplanet could have a temperature 251 K, well below freezing at 273K. At the moment, there is no solid evidence of an atmosphere there. Others reported that Trappist-1 system may have real trouble because of the abiogenesis zone, much closer to the 0.08 solar mass red dwarf where many more flares could destroy life attempting to evolve via abiogenesis using prebiotic molecules created in the abiogenesis zone.

Is E.T. phoning home today? Using this standard of science established for the heliocentric solar system - nothing confirms this view of nature at present or even if any type of life exists on Trappist-1 e or other exoplanets documented now. Probability creation stories are one thing, confirmation and testing (e.g., the Galilean moons moving around Jupiter) is another in my view.
