Written by who, humans or God?

We have already seen proof that some of the Bible was left out on purpose that directs us how to connect directly with God.

We have already found out that we only have a fraction of it created by the Catholic Church, the same Jesuits that have been torturing and eating children.

Juan quotes the Bible all the time, I dont think he ever said that all of it was manipulated or wrong.

If you go strickly by the Bible that most of the world sees, can you tell me who Cain and Abel mated with to create all the future generations?

Where did their wives come from? How did they begin the population of the Earth?
Can you tell me what the other 700 books in their original text said, because if you cant give me the original text translation, then it is only logical that some parts of it have been influenced by humans.

Not running down spirituality I know God, have been in his presence b4 God is very real.
Religion tho has been manipulated.

Many, especially those who are young in the Christian life, are at times troubled with the suggestions of skepticism. There are in the Bible many things which they cannot explain, or even understand, and Satan employs these to shake their faith in the Scriptures as a revelation from God. They ask, "How shall I know the right way? If the Bible is indeed the word of God, how can I be freed from these doubts and perplexities?" {SC 105.1}
God never asks us to believe, without giving sufficient evidence upon which to base our faith. His existence, His character, the truthfulness of His word, are all established by testimony that appeals to our reason; and this testimony is abundant. Yet God has never removed the possibility of doubt. Our faith must rest upon evidence, not demonstration. Those who wish to doubt will have opportunity; while those who really desire to know the truth will find plenty of evidence on which to rest their faith" Steps to Christ - Ellen White (pub 1892)
