Sciencism has history
Nearly all religions out there have a "truncated history". The moment of beginning of a religion is also the moment of death of its history. Christianity's history stopped shortly after Jesus's death. Islam's history stopped shortly after Mohammed's death. And so on. The problem with these religions is that when adherents need guidance for the present, they turn to the traditions and customs of long ago (thousands of years ago) for guidance. They completely ignore humanity's experiences during the last few millennia, when humanity learned so much from these experiences.
But Sciencism is different. Its history will never come to an end. Science was around at the beginning of the Universe, and it will be there at its end.
Sciencism is dynamic and changes with the times
Sciencism is closely related to Science. As new discoveries are made, science reveals to us lessons on how to be better than we are now. These lessons are recorded in Sciencism.
There are different "levels" in Sciencism
Everyone varies in intelligence (of all kinds), knowledge, experience, etc. In Sciencism, we believe that everyone should try to be the best they are by learning, experiencing, etc. and by this, a Sciencist will reach new levels in understanding. In Sciencism, a "level" system is used to distinguish between Sciencists of different levels of understanding.
