Science does not answer all questions. There are a lot of things in the world that science is unable to explain. Although science has helped us in sorting out some confronting issues and helped us to see things in different light, it has contributed to our human lives in diverse ways, but it has not answered some pressing questions such as The afterlife, the creation of man, the existence of God and things that happen in the spiritual realm.
The fact that science cannot prove some moral truth, it cannot explain how you feel, the degree of your love for someone or something. It shows that there a lot of things beyond science. Science does not know it all as it dies not to have an answer to everything.
Science doesn't make moral judgments. Specific questions of morality that science cannot answer include: Should we enforce the death penalty, what rights should animals have, what rights should be given to the mentally ill, and should we give gays the right to marriage? These are essential questions, but science cannot answer them because individual people are the ones who must make moral judgments.
Science may help us to understand the world, but it cannot make certain decisions as to what is morally just, right or wrong, good or bad. Science cannot enforce an opinion, but it can help us deal with cold hard facts.
The fact that there are so many things that are yet to be explained through science suggests there are a lot of things beyond science. While we appreciate the various works of science and the humongous contributions humanity has enjoyed through it, there are indeed fundamental things of life that are yet to be revealed through science. For example, how do you describe why the truth about the creation and existence of man hasn't been so much revealed through science. The truth about the existence of God is another thing.
The belief that most of the things that exist in the physical are just things that have been predetermined in the spiritual realm is another big issue. Also, we have so many people operating in different dimensions of spiritual influence, and yet there seems to be no explanation. These are just a few examples out of many things that make science seems limited in its operation to provide convincing information about some things.
