The gigantic difference

Is there really a difference between early human life and today. Your straight anwers are all yes. But they are also similar. Like today in my school we wrote on sticky notes and put them on walls and divided them into different catergories. My catergory was resources. I wrote in resources, technology, fire, weopons and tools,and toilet. These were all some of my ideas but I had lots more. After everybody did that in class the teacher siad something and everybody went up again and wrote comments and ideas. I went up and disagree with one of my classmates who was saying that fire was part of shelter and buildings. Now, because we are adavanced that does not make life that much easier. But it makes life a little easier. But still we have alot to learn.
