Here are five simple ways to say that for a 5-year-old:
- A horse can run very fast for a long time, so long ago people used horses like cars.
- Horses can gallop quickly and go far, so people once rode them instead of driving cars.
- Because horses can run fast and keep going, they were like cars a long time ago.
- Horses can run fast and don’t get tired quickly, so people used them to travel like a car.
- Long ago, horses were like cars because they could run fast and carry people far away.
Little note: that means before cars, people often rode horses to go places.
