Should hinduism be regarded as religion or just civilization, like romans and egyptians?

hindu name was given by persian invaders to indus vally people.hindus believe in different god and goddesses just like romans and egyptians use to believe earlier.hindus don't have any founder but a set of philosphies and vedas, hence it is a civilization.therefore, jesus was born to a jewish family, mohammed was born to a arab civilization family, buddha born to a hindu family and guru nanak born to a hindu family.but all founded different religions because hindus, jews, romans, arabs were on wrong track.so by saying that guru nanak was born to a hindu family, is was a hindu is a foolish and stupid thing to say. hindus was never a religion but a civilization.
