Back to the topic, To those of you who are christians, and believe in theistic evolution, do you believe the immaculate conception, if so why - since science says the virgin cannot get pregnant without sperm. ?
Good question. You see, nature itself is God's biggest miracle in this world. It works the way it does, because He is constantly making it so. God doesn't have to do miracles in nature; it's already made to work the way He intended. He does miracles not because He has to, but to teach us something.
Second - if you do believe in the immaculate conception, why would you believe evolution theory because science says so, when they don't even agree on it, and God says otherwise?
Secondary issue. Creationist ignorance of what "science says." Science doesn't say miracles aren't possible. It can't even comment on the supernatural, because the method is intrinsically limited to the natural universe.
Why is one possible but not the other when both defy modern scientific theory?
That secondary problem, again. Of course evolution is consistent with scientific theory. That's why scientists overwhelmingly accept it. And of course, miracles don't defy scientific theory, which can't even comment on such things.

Lastly if you still believe the virgin birth but don't believe in literal creation like it says in the bible,
See above. And the most influential writing in Christian faith about Genesis is
De Genesi ad litteram libri duodecim (translates to The Literal Meaning of Genesis) by Saint Augustine. And if you take Genesis as it is written, it is impossible to accept it as a literal history, as Augustine wrote.
what criteria do you use to determine what parts of the bible are truth and what parts aren't?
It's all true. Unlike YE creationists, other Christians accept all of it. They just don't adjust it to their personal preferences.
