Once upon a time it was a hollow.
Or a tree shade.
Or who knows what?
If you were to live in the open-air for a couple of days, what would you do? Find or build a shelter, no doubt. But there is no time for building. Look up! The clouds are coming, rush to find some cover. A hollow in an oak-tree is pretty good. A cave seems enough. Even some boulders may provide protection if you huddle tightly.
The grown-ups believe that there is a linear progression in the way people build their homes. In the same way in which we believe that we have better medicines and technology than before.
"What is progression?" you may ask. "A series of steps that leads from simple to complex." "What is complex?" you continue. "For now, think of it as the opposite of simple."
Archaeologists discovered traces of buildings and figured out how these may have looked like, how the people using them lived together, dressed and even talked. Yes, language is linked to building, you’ll find out later. Now keep in mind that building has to do with:
Structure Ornament Adaptability Togetherness
Along our building stories, we’ll light up these elements as, for instance, a specific ornament is not just a decoration, but a hint to a group’s lifestyle. After a couple of such readings of buildings, it will come easy for you to figure out the history of your surroundings and perhaps to invent new ways of dwelling in the future, when you’ll grow up.
