If Earth-like, then for sure it has well-developed life on it.

Any evolutionist (or would they prefer to be called "abiogenesists?) can tell you that.

Earth-like, in the context of this article, refers to an inner planet, not being a gas giant, but being a "rocky" planet, with a nickel iron core, similar to earth..

Mars is also an earth-like planet, although half the size and 1/10th the gravity, and a CO2 atmosphere..
Likewise, Venus is an earth-like planet, having a nickel iron core equal to earth, being equal in mass and size, but having a dense CO2 atmosphere, and being much too close to the sun, resulting in extremely high planetary temperature..
