How the Earth was without electricity?

The Earth without electricity had to be a very difficult for us, or so I think. It had to bevery difficult because the food had to be on fire, dry clothes with air or also with fire,use candles instead of lamps and many other things which are now made withelectricity. Nor had cameras if they would take a picture at that time tandrian be painted as a picture. Luckily there is now electricity because otherwise everything would be more complicated.
