Why were tool-making and language important for the development of human culture?

What do we use and do to maintain a healthy living? How did our early ancestors work together and make things in order to survive? The answers are very simple. Early humans communicated and made tools to produce food, water, stone- axes, and many other objects, in different shapes, sizes and textures. Without communicating they wouldn’t be able to work together, leading to working by themselves and maybe causing some problems. Communication back then was simpler and easier than ours today. They used their hands just like we use them today to explain something in general. Communication helped them to make tools too in order to survive. For example, like I said, they made stone- axes and bows and arrows and many other things to kill animals so they can feed themselves. They used sticks to make fire and heat themselves at night, or use fire as light if they cannot see appropriately. Without tools and language, most things wouldn’t have worked out for them. Even today, we use tools and language to reach our goal and to feed ourselves. Do you see how things are similar today like back then? But, of course, we have richer and more valuable tools for example, computers, machines, electronical objects etc… Imagine how much harder it was for them back then without electricity! I could talk forever, anyways, in conclusion, tool-making and language was important for their development to survive and to maintain a survivable community.
