Why is it controversial to say that the Earth could be the only planet in the universe with life?
Are there any planets that are promising candidates for extraterrestrial life so far?
Yes, there are a few planets that have been identified as being located in the "habitable zone" of their respective stars, meaning they could potentially have conditions suitable for life. One of the most promising candidates is a planet called Kepler-438b, which is located about 640 light years away from Earth.
