Text, MYTH versus REALITY

Myth side

Text, Earth-size planets are rare.

Reality side

Text, Astronomers estimate that roughly one in five Sun-like stars have Earth-size planets located in the "habitable zone," where water can exist as a liquid. Whether these planets are actually habitable or inhabited, however, remains a mystery. Both Venus and Mars are in the Sun’s habitable zone, but are not currently habitable.
