7th day adventist church is it main stream church or a cult church?

I add, I think that, there were many prophets, before the prophet Abraham, but they were preliminary of the modified-paganism, until the Abraham came, then he considered the maturing point of the modified-paganism, such as (the magic, the Taoism, the mysticism, the spirituality,the theology, the myths,..), but these the books were not written until this the time, where we established the philosophy the now, and the philosophy gather all the religions and modified it, and by the internet each book in each country transfer to all the countries, and we can have copies the now, thus I think the first mature religion was the modified-Paganism by the prophet Abraham by revelation from the Allah.
