Be Skeptical of the Hype in the Search for "Earth-like" Planets
estimate the number of potentially habitable (“Earth-like”) planets in the Milky Way galaxy by extrapolating from a small number of roughly Earth-sized planets we’ve found orbiting in the Goldilocks zones around “sun-like” stars. Never mind that these three parameters are often very liberally defined. More importantly, there is a world of difference (pun intended) between “Earth-size” and “Earth-like.” - TheStream

Your Say
People like to talk in terms of size and vast numbers and percentages, but I'd be surprised at all if we ever find another planet that's remotely habitable like earth.

I think we're overlooking a significant hypothesis: perhaps there is a planet that meets the conditions but everything in the world has all the air taken away from in between atoms and molecules. Why, that planet would be no bigger than a bowling ball.
