Science is perhaps the most successful human endeavor. We have explored the Universe and learned an incredible amount about nature in a very short time. We have improved the standard of living, the ability of humans to travel and communicate, our ability to grow and provide food for large populations, etc.
Science is a means of studying the physical world, not the approach to answer all important questions. Important fundamental questions about art, religion, the meaning of life, and our personal lives are outside the realm of science.
