Religion, rituals & population

We live in a country where we have 3 crore Gods & Goddesses, that’s what I learnt in my sociology classes back in college. 3 crore will be a combined population of few smaller countries in Europe. No wonder when we have such a strong population of Gods,the population of their followers should be more than 100 crores. Meanwhile these are the picture of the temple which we( me & my friend ) went to last Thursday. We’ll overtake China’s overall population by the year 2030-Sign of concern actually!
