Step-by-step explanation:
Before the advent of electric or gas lighting, people in Europe used to light fires on All Hallows' Eve to illuminate their homes and byways. In the past, their night skies were much darker and fires provided the only source of light.
On All Hallows' Eve, people lit fires not only for practical purposes but also as part of rituals and celebrations. This tradition was influenced by various cultural and religious beliefs, including pagan and Christian customs.
Some cultures believed that lighting fires could ward off evil spirits and bring protection and good luck. Others saw All Hallows' Eve as a time to honor and remember deceased loved ones.
