I don't define faith as anything, its not my definition but definition of professional linguists that is generally accepted all over the world. Religious thinkers have tried for centuries to make a logical argument in favor of religion but they failed and finally accepted that there is no proof or evidence of God, therefore there is a need for faith to believe in God. Faith basically means believing something without evidence (I already linked oxford dictionary definition). Most people follow a particular religion because they were born in a family that believes in the same religion. The reason why Pakistanis are Muslims and Portugese are Christians is the same reason why most Punjabis supported PMLN and Sindhis supported PPP (Its not based on logic but feelings, emotions, family/peer pressure and even superstition).
Also Proof and Evidence are synonyms, you can use them interchangably. I am not saying this, it comes from linguists and is generally accepted all over the world.

So far you have demonstrated that you do not know the definition of faith. That you do not know that Evidence and Proof are synonyms. As for you telling me what science is, I do not want to get into to much detail in one comment, but it seems like you have no idea what you are talking about.
There is no generally accepted scientific method, some people come up with a hypothesis and try to prove it, some people try to disprove their hypothesis and formulate a new hypothesis from the results (The falsification method). Others like Sir Isaac Newton did not even need a hypothesis. But the end result is the same, the purpose is to answer questions about the universe, unlock mysteries, make new discoveries and improve the lives of human beings. From the last few hundred years we can see that science has done a spectacular job at all of them.
