At the beginning of this young community, I thought it might be helpful to make a clear distinction between the definitions as they differ greatly in their explainability. Contrary to some opinions that can be heared, the statements a) there are one/more divine beings and b) no divine beings exist are logically equivalent.
Of course, evidence-based beliefs are always preferable. But that depends on how detailed the foundations of your beliefs are. Religions tend to explain abstract things very simply and in a way that is easy for everyone to understand. They just give a different interpretation of the phenomena surrounding them, as we have done here. It really depends on how much information and how detailed your scientific basis is, because the simpler explanations often deviate greatly from reality.
In conclusion, however, I would say that what is really important is that every faith, be it atheistic, agnostic or theistic, leads to a good life for oneself and one’s fellow human beings.
