Dwelling, on the subject

Just like Batman and Green Arrow, we start out with our base in a cave. We practice early forms of graffiti that inform generations what life was like in our (pre)time.

Do we pitch a tent the first time we're out in the open - or are some of us sleeping in trees like our primate cousins?
What was the first residence that could properly be called a hut? Where did our ancestors shack down for the first time?

When is a house a home, okay, fair question. Here's another: when is a house a house?

The oldest building is variously the Neolithic temple of Hagar Qim or  the Pantheon.

The earliest bed where we lay our head? The figure was only revised in 2011 to 77,000 years ago, 50,000 years earlier than previously thought. And we've also found a 'kitchen' dating back a million years - this predates our accepted knowledge of human's use of fire by 300,000 years.
