Is there any religion, which is based on science and reasoning (not faith and God), and made for?

First I want to commend you for wanting to base your beliefs on fact and reason. Many people today readily accept what religious leaders teach them with little to no personal effort to prove or disprove what is taught. Religion is not just a system of laws and principles that govern a persons life, but it should be a way of life effecting a persons thoughts, words, and decisions. Being such an important aspect of life a person must take very seriously his/her obligation to seek out and find truth. I personally made that decision in 2006 and have since educated myself in the common beliefs of the majority. A publication that was of great benefit to me is entitled "mankind's search for God". I'm confident that it will answer many of your questions. You can download it at JW.org.
