I think it only makes sense that there are other habitated planets in the universe. It's too big for there not to be.
It absolutely makes sense in theory.
But 'other earths' are hard to detect.
With exoplanets were like that drunk guy that the policeman found pacing around under the street lamp in the middle of the night. The cop asked what he was doing. He replied "Im looking for my car keys. I think I lost 'em somewhere over there[ pointing off the road to a dark field]. The cop asked " then why arent looking for them over THERE?". He replied "because the light is better over here".
In the first few years after they accidently stumbled upon the first exoplanets in 1994 they been finding only the planets they are easy to find. Which are extremely big planets that are extremely close to the parent star: "hot jupiters"- Jupiter like planets closer than mercury to their star. Finding small things at a moderate distance from the parent star (like earth) is a challenge that only now they are starting to master.
