how did the first humans survive?
When humans, or Homo sapiens first evolved, we were just like any other chimpanzee or gorilla - there was nothing special about us. Then we developed tribes such as the Indigenous Australians who split up into many groups of people who speak different languages and has a leader. In these tribes they strived to survived. Men used tools such as spears and boomerangs to hunt and women went out in their woven baskets to collect fruit and yam underground. They were very successful in the wild, and had different techniques in how to catch food.
How did humans advance over time?
In other countries such as Mesopotamia where the soil was very fertile, humans began to start farming and raised animals and grew crops to eat, instead of hunting. This led to big civilizations which involved a larger group of leaders such as a priest, pharaoh or government. Then humans were treated differently to each other - in Ancient Egypt, there was a ruler called a Pharaoh, then there were slaves and workers which were treated badly compared to their gods. This was because they had taken control of the land around them, and had developed intelligence so that they could create a civilization such as this. Humans then began to dominate the world, growing large cities and countries with high levelled governments and democracy systems. Systems around the world were then being controlled by human technology.

What are humans now?
Humans are now the rulers of this planet. This is because we can work together in large numbers and flexibly as well. Working flexibly means that we can work in a way where we can change our roles to complete a different task. When we collaborate, we not only build good things such as corporations and businesses but also bad things such as jails, prisons and slaughterhouses. But human collaboration has led us to this point where we dominate Earth. Because humans now are no longer 'animals', we have the time to learn many things about the world around us. This include science, mathematics, geography, astronomy and many more. We now call learning these things 'education', which is now essential to know the basics of to be able to survive in the modern world.
How are we affecting the environment?
Humans are affecting the environment in many ways. This includes polluting the atmosphere and water, killing off species of animals and plants, using up precious fossil fuels and wasting freshwater. In a few hundred years, if we continue harming the environment, Earth would not be suitable for a lot of life. Humans will then die out, but life will take this chance to evolve further and develop into more complex species. We might not know this yet, but what we are doing will mainly affect us.
