One face of the moon is always toward the Sun - and one side always away from it... Freezing cold forever and blistering hot on the other... A small band between the two extreams is the only area a human could “live” - and for what? Mars is better choice - or a moon on a more distant planet...
Not so! One face of the moon always faces the Earth, but all of the Moon's surface gets sunlight during the 28-day lunar month.
When the Moon is new, the far side is in full sunlight; when it's full, our side is in full sunlight.
