i presume you are interested in the philosophy of Science socrat so i will ask you this-
can a process that hasnt been observed today and is claimed to have happened in the absence of a man documenting this process be classified as "science"?
and- can a process that has actually been observed today be extrapolated backwards and be classified as "science" when speaking for the time periods this process is alleged to have happened in the past also without a man documenting this process?
