Obviously, the natural sciences operate in the real world. Proof is not only unnecessary in the natural sciences, it is impossible. Therefore, your statement is incorrect.
What the fuck are you smoking? Proof is absolutely needed and OBSERVED in the real world..It is the basis of REAL science..
You must believe in the common core version of science... its whatever we tell you it is.. no evidence required..
You have just come as close to PROVING you do not have any form of science degree as it is possible to come.
