If lights weren’t invented, how is our life would be?
 If lights had never been invented, our lives would be significantly different. Here are a few ways:

1. Shorter days: Without artificial light, we would be reliant on natural light from the sun. This means that once the sun sets, we would be in darkness. Our days would be much shorter, and we would have to go to bed earlier and wake up earlier.
2. Limited productivity: Many of us work or study after the sun goes down. Without artificial light, we would be limited to working during daylight hours only. This would significantly impact productivity and could hinder economic growth.
3. Limited social activities: Many social activities take place after dark, such as dining out, attending concerts, or watching movies. Without artificial light, these activities would not be possible, and our social lives would be limited.
4. Limited safety: Artificial light plays an important role in ensuring safety. Without it, it would be difficult to see in dark areas, increasing the risk of accidents and making it easier for criminals to commit crimes.
5. Limited medical care: Medical procedures and treatments often require artificial light. Without it, many medical procedures would not be possible, and patient care would be compromised.
6. Limited scientific research: Artificial light is essential for many scientific experiments and research. Without it, we would not have made many of the scientific discoveries that we have today.

Overall, the invention of artificial
Without the invention of lights, life would be much darker and more difficult. We would not have access to the same level of entertainment, work would be much harder and more dangerous, and travel would be much more difficult. In addition, many essential activities such as reading and writing would be much more difficult.
