How do you deal with a religious family?

So, there was a common written source for all three which was made up. Which would mean that the authors themselves were gullible morons and whoever wrote the source lied about it.

You have thus-far missed my point entirely. It is not helpful to be so divisive in an argument, especially when you have no evidence. Any dialogue you open with a Christian in that way can only end badly - you are in effect planning to fail. If you can't even answer my points, and listen to my argument coherently then how could you be expected to hear other points of view?

I do claim that they were liars - their writings are full of ridiculous stuff about gods and Pharaohs being gods in human form. What it tells us about their culture is a different matter - we get that from reading between the lines and using other sources to separate fact from fiction.

Right, so then when they find graves with inscriptions reading "here lies such and such" they're lying?

You have very little appreciation of history and how historical records are considered.

I don't believe the Exodus ever occurred - I believe that is a myth. I don't believe that it's a deliberate "lie" I believe that the Israelites beliefs were written down into the Pentateuch (almost everyone believes this FYI including Jews and Christians). That doesn't have any bearing on the historicity of other writings though, whether those writings are included in the 49 writings (66 "books") of the Bible or elsewhere.

Also, you have been unable to back up any of your claims with evidence. This is the problem with your position - you take an extreme view that not even sceptical scholars take, that all the authors are inherently liars, this polarises you from the discussion even away from the sceptics who would prefer to have you on their side, all the while you cannot back up your view with any evidence other than facts that Christians already know about such as there being numerous minor textual inconsistencies.
