Have actually read the bible? You sound like somebody that hasn't. Contradictions start right from Genesis as 1 contradicts 2 and so on. If you want to explore contradictions in the Bible, I suggest this website: http://bibviz.com

Click on any of the red semi-circles and you will see information about the contradiction(s) it represents.

There are surely many, huh?

Here's a small excerpt of questions that have different answers in different parts of the Bible, you can find a much more extensive list at the bottom of the website I gave you.

There are more than 750 contradictions listed there, you can look at them and use your right thinking to check with the Bible and see if it actually agrees with itself.
