1. Scientists follow the methodological naturalism, i.e. Science looks only for god-less explanation of nature and the effects. The probability of Darwinism is near zero, but because it is not believed to be exactly zero, the Darwinism is Scientific.
Spoken like a person who has never study science before. Never understood even the basic.
Science isn’t seeking godless explanation, but a natural explanation for natural phenomena or natural processes.
And the probability of any scientific theory being true, are dependent on testable observations (eg evidence, test results from experiments). The quantity of evidence or test results will determine if it is true or not.
And there is no such thing as Darwinism.
It is called Theory of Evolution, one of the biological and evolutionary mechanisms is Natural Selection, not Darwinism or Darwinian Evolution.
Darwin never named anything after himself. He called it Natural Selection, not Darwinism.
And there are more to Evolution than Natural Selection - other mechanisms, such as Genetic Drift, Mutation, etc.
Lastly, there are more to Natural Science than just Evolution. Evolution is only one field in biology, and biology or Life Science is just one broad branch of Natural Science. The other broad branch, is Physical Science.
Physical Science included other branches:
- Physics
- Chemistry
- Earth Science
- Astronomy
Natural Science differed from Social Science.
Social Science include psychology, anthropology, archaeology, law, economics, political science, etc. Meaning any study of human activities, human cultures, human behavior, etc.
Natural Science (Physical Science & Life Science) have nothing to do with atheism.
Atheism is only question about the existence of god...and people who are atheists, simply don’t believe in the existence of god or gods, nothing more, nothing less. Such question has nothing to do with Natural Science.
