http://www.religioustolerance.org/chr_jcse_his.htm has some sources for this, but I honestly don't care.
Whatever the truth is (assuming it could be proven), if it isn't aligned with a church doctrine of whatever sect, that sect will reject it and continue to teach whatever lies* it likes.
After all, with all of these christian churches and sects, they can't all be telling the truth. If it isn't truth, it's B.S.
Nor can all of the churches, temples, etc. sects of all religions all be correct.
Of course, with churches, we can redefine "truth" to mean "what we say", so facts don't matter when discussing them with the religiously afflicted.
The safest bet is that they're all probably at least partially wrong, and likely very, very wrong on many important points.
If a particular sect believed "Jesus is a magical invisible half-frog, half man that floats through the air and grants good wishes as he sees fit.", any fact that discounted half-frog or invisibility would be heresy.
So go ahead and make up any story you like. It will be no less wrong or accepted or rejected than any other opinion based on study and archaeological science.
*There's a difference between speaking out of simple ignorance and lying. Consciously deciding to ignore other information, and tell only the version of reality you want other people to believe in is lying by any definition of lying that means anything. Naturally, given the religiously afflicted tendency to treacherously redefine simple terms, lying is only disagreeing with a religious authority.
