A scientific theory is a well-substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experiment. Such fact-supported theories are not "guesses" but reliable accounts of the real world. The theory of biological evolution is more than "just a theory".

[ 1 ] The term law has diverse usage in many cases (approximate, accurate, broad, or narrow) across all fields of natural science ( physics, chemistry, astronomy, geoscience, biology ).
The prevailing scientific hypothesis is that the transition from non-living to living entities on Earth was not a single event, but a process of increasing complexity involving the formation of a habitable planet, the prebiotic synthesis of organic molecules, molecular self-replication, self-assembly, autocatalysis, and the emergence of cell ...

Scientific evidence. Scientific evidence is evidence that serves to either support or counter a scientific theory or hypothesis, [ 1] although scientists also use evidence in other ways, such as when applying theories to practical problems. [ 2] Such evidence is expected to be empirical evidence and interpretable in accordance with the ...
