Science works, it has worked in the past and will continue to work going forward. No matter how strong your faith is in your particular deity or religion, it will not stand the test of time like science will because science is simply an honest exploration in search of the truth. That is why science will win.
I see at least 2, what I see as, fatal flaws in your discourse.
First, I think you are conflating the purposes of religion and science; they seek to answer distinctly different questions. Religious endeavors seek to answer meta-physical questions such as does God exist? How should I treat others? Is there life after death? What is my purpose in life - why am I here? Science cannot address these types of questions.
Science is designed to address questions about the physical world. Its pursuits are limited to things which we can experience with our senses or can convert into a form which we can experience with our senses (example: we can't detect radioactivity directly with our senses but have developed instruments that can detect radioactive particles and then converts it into a format that we can observe with our senses).
Sure there is some overlap in the two systems, but the problem comes when that overlap becomes too great. When you use science exclusively to answer these types of meta-physical questions it becomes a type of religion, not in the strictest sense of belief in and worship of a supernatural being(s), but in the more general sense of a set of beliefs that relate humanity to an order of existence. It becomes a set of beliefs that attempts to answer the same questions that I mentioned as the purpose of religion.
The second flaw I see is that you seem to attribute all human failings to religion. When in fact, human corruption is the base problem and religion simply becomes a justification for personal conduct. You seem to believe that should we eliminate all religion that would somehow eliminate human corruption. I don't believe that to be the case. We have seen a significant departure from organized religion in recent years, and yet I don't think it can be shown that human corruption has significantly improved.
Science is important, even crucial, to our understanding of reality, I would agree, but I don't believe it can answer all of our questions; that it can address all the challenges of the human condition.

Whoever calls me ignorant shares my own opinion. Sorrowfully and tacitly I recognize my ignorance, when I consider how much I lack of what my mind in its craving for knowledge is sighing for. But until the end of the present exile has come and terminated this our imperfection by which "we know in part," I console myself with the consideration that this belongs to our common nature. - Francesco Petrarca
"Nothing is easier than to persuade people who want to be persuaded and already believe." - another Petrarca gem.
