What makes us human is a complex question that has been explored by many fields of study. Here are some key features that are often cited:

• Bipedalism: Walking on two legs is a defining characteristic of humans and sets us apart from other primates.

• Language: Humans have the unique ability to communicate complex ideas through language, which has allowed us to develop culture and civilization.

• Tool making: Humans are skilled at creating and using tools, which has allowed us to adapt to a wide range of environments and challenges.

• Forethought: Humans have the ability to imagine the future in many possible iterations and plan accordingly.

• Imagination: Imagination is what makes us "human". The ability to believe in an invisible idea, concept, the development of proof, and then create the tools.

• Brain: Our brain is what makes us human, and our brain develops under the control of our genetic makeup. The human brain is well known to differ considerably from the chimpanzee brain in terms of size, organization, and complexity, among other traits.

• Free will: Humans have the ability to make choices and decisions based on their own desires and beliefs, which sets us apart from other animals.

• Culture: Humans have developed complex social structures and cultural practices that are unique to our species.

It is important to note that there is no single answer to what makes us human, and different fields of study may emphasize different features. Ultimately, it is likely a combination of biological, cognitive, and cultural factors that make us who we are.
