The bible exists in many forms and variations. What we call the bible now exists in two basic forms.
1) The King James Version
2) The Holy bible.
The first known bible was created by the Council of Nicea in 325ADE. The council collected various stories from myths and legends and compiled a book that politically favored the authority and concentration of power to Emporer Constantine. Which was the purpose of the council in the first place. There were some glaring omissions in that bible.
1) The resurrection.
in fact, the resurrection didn't come about until a few hundred years after the Council of Nicea.
Over the years the "bible" has been heavily edited and altered to fit a new political narrative.
1 Esdras (Vulgate 3 Esdras)
2 Esdras (Vulgate 4 Esdras)
Tobit.
Judith ("Judeth" in Geneva)
Rest of Esther (Vulgate Esther 10:4 – 16:24)
Wisdom.
Ecclesiasticus (also known as Sirach)
Baruch and the Epistle of Jeremy ("Jeremiah" in Geneva) (all part of Vulgate Baruch)
Many books of the original bible were just thrown out for this reason. In 1684 14 books were eradicated from the bible.

In 1611 the bible was translated from Latin into English. There were many errors as a result.
No one knows who wrote the "gospels". They first appear in the 2nd century. There are NO 1st hand accounts ever found that date to the first century....absolutely none.
Those glaring problems aside the biggest problem with the bible are that outside of itself there is no verification that anything in it is true. No Roman, Greek, or Egyptian records.
Also, the bible is limited. It has no knowledge beyond what was known in the 4th century and is geographically limited to the Roman Empire of the 4th century.
Probably the most problematic thing with the bible is its innate vagueness. For a book that demands that it be taken literally it is monstrously vague about many points. Alos it is filled with glaring contradictions.

These points are the most important factors in not taking the bible seriously.
1) It isn't scientific, does not meet the scrutiny of being valid, no verification, no peer review, nothing to substantiate anything in it.-CANNOT BE USED TO ANSWER SCIENTIFIC QUESTIONS
2) It isn't historically accurate.-CANNOT BE CONSIDERED A HISTORICAL REFERENCE
3) Its origins are dubious and questionable-CANNOT ACCEPT ITS VALIDITY DUE TO UNKNOWN AUTHORSHIP.
4) It bears no resemblance to its original form-INVALID DUE TO POLITICAL MANIPULATION
So for you believers in the bible that come on this forum and wonder why you are pointed out as trolls for using bible quotes, now you know. The bible isn't valid. It isn't proof of itself because of not only the obvious (it isn't an independent source of itself) but also itself has changed drastically over the centuries.
