As a student of History, Archaeology, Astronomy, Evolution's Biology or Geology ... The Past in its Relative relevance to the Present, and Future ... is all there is ... thus, Past is critically important.
As Theoretical Physicist, Oracle, Astrologer, Astronomer, or Palmist ... the Future, remains most important ...
But as a Human, the Present is "all" that counts ... For we always live in the Present ... what happened, has its limited applications ... and
Theories, are mere prophesizings ... nothing but wild, or at times, calculated Speculations.
