Earth like planets are far too rare, and even if you have one evolution does not veer towards intelligence but rather away from it as brains are energy expensive. Yes I'm aware of the kepler finds but we have no way of knowing if those worlds have the liquid core needed for life to evolve.
I have to repectfully disagree. The precentage of earth size planets is still unknown. Astronomers only recently were able to find these small planets.
Also, water is very common in the universe as it is a byproduct of the star formation.
BUt you need alot then just that. You need a large moon to skim atmosphere and slow rotation, you need a magnetosphere which means a spinning core. You also need active plate tectonics. And that is just for simple life too evolve.
To-morrow, and to-morrow, and to-morrow,
Creeps in this petty pace from day to day,
To the last syllable of recorded time;
And all our yesterdays have lighted fools
The way to dusty death. Out, out, brief candle!
Life's but a walking shadow, a poor player,
That struts and frets his hour upon the stage,
And then is heard no more. It is a tale
Told by an idiot, full of sound and fury,
Signifying nothing.
