Is there any possibility that English could be matched by another language as the most used language across the world?

Simply, the answer is no , no languauge could match english languauge at least on short term.

Why? here is an explanation why English is the sole global language.  A language achieves a genuinely global status when it develops a special role that is recognized in every country. This might seem like stating the obvious,but it is not,for the notion of ‘special role’ has many facets. Such a role will be most evident in countries where large numbers of the people speak the languageas a mother tongue – in the case of English,this would mean the USA,Canada,Britain,Ir eland,Australia,New Zealand,South Africa,several Caribbean countries and a sprinkling of other territories. However,no language has ever been spoken by a mothertongue majority in more than a few countries (Spanish leads,in this respect,in some twenty countries,chiefly in Latin America),so mother-tongue use by itself cannot give a language global status. To achieve such a status,a language has to be taken up by other countries around the world. They must decide to give it a special place within their communities,even though they may have few (or no) mother-tongue speakers.

English is the third most used language in the world. Mandarin is first, Spanish 2nd, Hindi/Urdu 4th and Arabic 5th.

I don't think so. It will take decades for English to be ranked below the third most spoken language around the world :) 

We have to invent a country that was not ruled by English. If this possible then that country's language can match.

In fact I have not used a word "discover" in place of "invent". Hope you will understand this.

Is it possible to invent such country? 

Yes, the same as English eclipsed French. But not for a while.

It is really good to unite all hundreds different languages around the world & unite them all in one international language for a better & easier communication between them. It won't make any difference which language to use; wheather English, French, or Arabic but the matter is how fast & easy to use to be applied & spoken by all.

PEACE BE UPON YOU

We have learned from history, a photographer of events that the constituents of any people is the language that translates its mastery of civilization. The have many civilizations throughout history and spread their language over the breadth and People sometimes decades, appeared to the Greeks and their civilization and Persians and the Romans and the Islamic Caliphate, and all shone language superiority of civilization in various fields that appeared so-called new world which America boasts diverse peoples led by the British and the diversity of culture, the modern civilization of a new state is the United States of America, which united with Britain, with colonies most across the world showed the English language that expresses the components of what we have reached the first country in the world today an American and then never be certain that in the distant future will remain English are the most reference as long as we believe that there are civilizations built on the ruins of other civilizations still so basic ingredient remains raced civilizations as it is today evident in clumps of State and preceded in control of the world's tenets of civilization.
