There are some documents “with scripture proofs” included.

I went, and I saw a website with the philosophies of men mingled with scripture.

I saw doctrines created by specific churches that have no authority beyond that church. Some of these decrees are accepted by other churches, but that does not mean that these man made tenets of their church should apply to me for I am not in their church.

I saw nothing that required anyone to believe a specific doctrine to be a Christian. Do you have more?

In regards to the historic church documents, maybe try taking off your “but there are so many churches and all the doctrines are created by man” glasses. :-) The other place I can point you to is the Bible. I am curious, do Mormons read the Bible often, either in worship, study groups, or for personal edification?
