A scientific theory is best described as a well-substantiated explanation of an aspect of the natural world. It is based on a body of evidence that has been repeatedly tested and confirmed through observation and experimentation. Unlike a mere guess or hypothesis, scientific theories encompass a comprehensive understanding of the underlying principles and mechanisms governing natural phenomena.
