Unfortunately for you, you can't prove that there is any real error. Matters that conflicts with your beliefs are not errors, if you can't prove your beliefs correct.
Start right at the beginning: Genesis.
Genesis chapter 1 says the first man and woman were made at the same time, and after the animals. But Genesis chapter 2 gives a different order of creation: man, then the animals, and then woman.
It is not a matter of conflict with any beliefs. It is impossible for both scenarios to be true -- and therefore, using only 2 brain cells, one must be false.
Okay, New Testament: Matthew 2:13-15 depicts Joseph and Mary as fleeing to Egypt with the baby Jesus immediately after the wise men from the east had brought gifts. But Luke 2:22-40 claims that after the birth of Jesus, his parents remained in Bethlehem for the time of Mary’s purification (which was 40 days, under the Mosaic law). Afterwards, they brought Jesus to Jerusalem “to present him to the Lord,” and then returned to their home in Nazareth. Luke mentions no journey into Egypt or visit by wise men from the east.
It is not a matter of conflict with any beliefs. It is impossible for Jesus to have both gone to Egypt and NOT gone to Egypt. Now, using only 2 more brain cells (which leaves you billions for other things), one must be false.
There are many, many, many internal contradictions like this -- too many to bother with here. But let's look at just one more: Ezekial 18 says, "
The son shall not bear the iniquity of the father, neither shall the father bear the iniquity of the son: the righteousness of the righteous shall be upon him, and the wickedness of the wicked shall be upon him." Of course, that's simple justice. And yet, when David sinned with Bathsheba, who died at the will of God-- taking a cruel 7 days to do so? Their child. So God doesn't even bother paying attention to his own rules.
Nope, sorry. The Bible is the work of humans, and only the work of humans.
