Google is not a valid source. It does not define 'science' or 'philosophy'. It does not own either word.
Philosophy is an argument and it's reasoning behind it. About the only rule in it is that the argument and it's predicates must come from the one making the argument, not by stealing the arguments from others.
Philosophy defines 'science', what it is, and why it is defined the way it is. It also defines 'religion' and why it is defined the way it is.
Philosophy also defines 'real' and 'reality' and why it is defined the way they are.
Science is a set of falsifiable theories. That's it. That's all. It does not use supporting evidence. Only religions do that. Science requires no license, credential, university, government, scientist, group of scientists, voting bloc, or any political organization.
Among the theories denied by the Church of Global Warming for example:
The 1st law of thermodynamics: E(t+1)=E(t)-W where E is energy, 't' is time, and 'W' is work.
The 2nd law of thermodynamics: e(t+1) >= e(t) where 'e' is entropy, and 't' is time.
The Stefan-Boltzmann law: r = C * e * t^4 where r is radiance in watts per square area, 'C' is a natural constant, 'e' is a measured constant known as emissivity, or how well a surface can radiate light, and 't' is temperature in deg K.
Each of these are theories only. They are not proven True. They could be falsified at any time. So far, they haven't. They are still theories of science, and they cannot just be discarded.
Science has no theories about past unobserved events. There are, however, many nonscientific theories about such events, including:
The Theory of Abiogenesis, the Theory of Creation, the Theory of Evolution, the Theory of the Big Bang, and the Theory of the Continuum. All of these remain circular arguments, with arguments extending from them, the very definition of a religion. They may be True, they may be False. We simply don't know. They must be taken on faith, and on faith alone.
Someone that tries to prove a circular argument commits the circular argument fallacy. This is what a fundamentalist does.
