I believe the bible is man-made, to me it quite obviously is. The superstitious tales about the existence of giants (Deuteronomy 3:11), witches and necromancers that could reanimate the dead (Deuteronomy 18:9–12, Leviticus 20:27, 1 Samuel 28, etc.), and nephilims - the product of a divine being and a human woman (Genesis 6:1-4) all point to the bible being written by fear ridden, ignorant men in the bronze age. The fables in the bible are ones only the superstitious COULD believe; from Elisha being taken to heaven on a "chariot of fire" with "horses of fire" in a "whirlwind" (2 Kings 2:11), to Joshua stopping the moon and sun (Joshua 10:14) (this clearly shows the ignorance of the time; why not just stop the Earth from rotating?), these stories are clearly fictional.
Then, of course, is the way that the bible treats women; do you genuinely think a god would create men and women equal but then write in the bible that women are the property of men (Genesis 3:16, Exodus 20:17, Exodus 21:7, Deuteronomy 22:28-29, etc.)? The way the bible depicts women is truly appalling, and it has warranted men to rule over women for centuries. Likewise, the bible also condones slavery (Leviticus 25:44-46, Exodus 21:2-6, Exodus 21:7-11, Exodus 21:20-21, Ephesians 6:5, etc.) which is just as detestable.
To add to all this, there are many, many, many contradictions throughout the book. Though there are too many to really put in this short post, but I will provide a few. First, does god tempt people? According to James 1:13, he does not. However, everybody knows the story of when god tempted Abraham in Genesis 22:1. Next is the radical differences with the genealogy of Jesus displayed on both Matthew 1:16 and Luke 3:23. I shall end with the number of people who saw Jesus’s resurrection. It was 1 woman, according to John 20:1. 2 women, says Mathew 28:1. 3 women says Mark 16:1. Luke 24:10 doesn’t give an actual number, but it says at least 5 women were there. Like I said, there are countless others, but I don’t want to write a novel.
Finally, there’s the problem with the story itself. All powerful, all knowing god created everything, and after years of god slaughtering hundreds of thousands of people (1 Chronicles 21, Deuteronomy 3, Joshua 6, 2 Kings 10:18-27, etc.) because of the sin HE created (Isaiah 45:7), he decides the only way to forgive himself (Genesis 1:27) was to sacrifice himself (John 10:30-33) to himself. As Thomas Paine put it, “it is impossible to conceive a story more derogatory to the Almighty, more inconsistent with his wisdom, and more contradictory to his power, than this story is.”
(Please refrain from responding with anything along the lines of “You’re a heathen and are going to burn in hell” or “God is going to enjoy burning you!”. I wrote this to have a semi-intelligent discussion rather, than having hate being spewed at me)
