How do you deal with a religious family?

The textual basis for the resurrection in the Bible originates from at least two different witness statements. As I just mentioned there's no guarantee that they are independent, but there's no proof that they aren't either.

You mentioned more than that - you had a whole laundry list as to why those witness statements are not credible.

A theory doesn't have to be true to be a valid theory, on the contrary it has to be falsifiable.

Actually, it does. Or more specifically, it needs to have credible evidence supporting it. At best what you have here is a valid hypothesis.

The theory that Jesus was resurrected is a valid theory, and it's falsifiable.

Given that it doesn't have any credible evidence supporting it....

The theory that Jesus was not resurrected is also a valid, falsifiable theory.

It has more evidentiary support for it than the other one - specifically that as a general rule, the dead don't get up after three days.

Thus either is a valid theory, and neither can be proven.

Absolute proof is a nonsensical notion - evidence can be and should be presented for both.

However there is, certainly, evidence for either case and the quality of that evidence is debatable.

What debate? You argued - very persuasively, I might add - that evidence for the position is not credible. I agree. Debate over.

But... it's also inconsequential since Christianity is a faith-based belief and doesn't require proof. That is to say that Christians don't need to prove their claim to believe it, they believe it because they have faith.

And if they limit themselves to that, that would be fine. But if they want to convince others and impose those beliefs on others, then they need actual proof.
