There are a lot of differences between humans and machines. In fact, these differences do not require any logical thinking as they are very simple to state out. First, humans are natural creations. Most people believe that humans were created by God, together with other living organisms. On the other hand, machines are created by human beings.
In our world today, there are a whole lot of machines which have been designed for different tasks. The fact that machines do not have life is another difference. Machines are made with different kinds of materials, both organic and inorganic materials. In contrast, humans have their bodies made with flesh, blood, and bone.
Machines cannot think on their own except if there is someone operating them, whereas humans have a brain that makes them act on their own, and they do not need to be controlled by anything before they can act. Another difference is that humans can easily express their feelings and emotions, whereas machines cannot do this.
