Archaeology has frequently proved the Bible to be false as a historical record. Finds are often interpreted to fit biblical commentary. The "mighty city" of Jerusalem was a mud hut village until the time of the Greeks and Romans, yet it is portrayed in the Bible as a glorious Hebraic creation. There are numerous examples of such "literary license," a notable one being that Nazareth, for example, didn't even exist at the time of Jesus's purported advent.
One cannot claim a book that is written exclusively from the perspective of one sect to be a credible history. If the Bible is history, then only Jews are the chosen people of God and all others are detestable and to be done away with.
Perhaps the greatest evidence against an Almighty God living in the Palestine during the 1st century is his inability to attract significant notice (much less endorsement) in the detailed contemporaneous history. There is hardly any mention of this Almighty anywhere in the historical books of his time-proving that such an Almighty did not live at all. Philo, one of the most renowned writers of the Jewish race who was born before the beginning of the Christian era, and who lived (around Jerusalem) much after Christ was crucified does not say a single word on Jesus the miracle maker.
The 1st-century Jewish historian Josephus believes the resurrection story as an interpolation. Josephus devotes more space each to John the Baptist and James, and while reporting much minutiae over the entire period during which Jesus lived. There is some passing mention of Jesus in his writings. Some of his utterances are believed to be later additions. Other historians like Cornelius Tacitus and Tranquilus Suetonius have passing comments on a new sect and are silent on Jesus or his ministry.
If Jesus was an Omnipotent, Omniscience and benevolent Deity He would not go unnoticed in his times. He is said to have raised the dead from their graves, walked over waters, and fed 5000 people from five loaves of bread. He gave sight to the blind, hearing to the deaf and made the crippled walk. But he had to be betrayed by one of his own disciples to the authorities! It defies common sense!
We can glean nothing from the Gospels about Jesus--what did he did or what he said. From the moment of conception to his death incidents and stories that were the common characteristics of the mythical gods like Osiris-Dionysus. Mithras, etc. were added on to the life of Jesus and such layers and layers covered the reality.
The contradictions and immorality in the stories of the Bible are not because God is flawed or evil, but rather because the Bible writers are flawed as they are the ones who created the entire thing independently of any god.
The Old Testament contains stories of creation and original sin to explain the misery and suffering of man, a great deluge, and narrations on human trafficking, ethnic cleansing, slavery, indiscriminate massacre and vengeance. The New Testament is about a faith healer and reformist preacher who was crucified by the Romans at the instigation of the Jews. Preacher-writers made him a ‘Son of God’ after the fashion of the mythical gods born of Immaculate Conception and doing so many miracles including raising the dead. Like the gods before him, Yeshua was made to resurrect. Later on, he was made into the Almighty God. But the reality could have been he was born, lived and died a Jew without ever thinking of instituting a new religion.
