Greetings dear brother
You are right if we take the ancient history and modern history and consider it then we can fully understand the contribution of science, what is its definition and what it means. They used tree leaves to cover their private parts, took even tree leaves as food, On the other hand how happy we are living now, as you said vehicles were not there in earlier times animals were used, animal water was used to go from some to Pakistan but now it is transported by vehicles, very nice presentation for you. Good luck herein competition
