Science is a tool created by humans to help them interpret the outside world in a language commonly understood by all of us.Humans depend on it for survival. Also the commonly understood medium of science is useful for mass transmission of our learning to others. Like all tools,science can be useful in a context-ie within the limits of our sense organs.
Can something which cannot be explained scientifically, exist in reality? Are other forms of life like plants,animals etc use science as we call it today?Understanding the limits of a tool and it's contextual relevance makes it realistic.Can this make us humble and still searching instead of making final conclusions ? Earth which was considered flat at one time ,was disproved as we went along our scientific journey.
Is science useful? Surely yes.Is it's findings final? Maybe not.
