Although modern wonders don’t admire us, we are used to them, daily findings don’t seem very important for us, we have still saw difference between our modern world and the Ancient world.
The first wonder is international travel. The second wonder is medical science. The third wonder is the internet. The fourth wonder is agriculture. The fifth wonder is space travel. The sixth wonder is the Olympic Games. And the last wonder is that we are still here.
I want to tell about the last wonder because I think it has been the most wonder as the Ancient World as our time. Although a lot of countries have had nuclear weapons for over 50 years, although a lot of politicians want to capture territory, although arms race is gone on, people have been using different ways, including illegal. Some people try to kill us, others try to help us.
Despite the endless chaos, we are still here, we are still alive. This is a really wonder as the Ancient World as the Modern World.

Tips:   
Generally speaking, when you have a new subject, you should start a new sentence.  
Use a thesaurus to find synonyms to vary your writing instead of repeating the same word (like wonder) over and over.  http://www.thesaurus.com/browse/wonder?s=t 
Learn how to use the word "although" correctly.
Stick to the point.  You said you were going to talk about "us still being here" but your subject matter is all over the place and is hard to follow.
