I never said that science and christianity had to be mutually exclusive. Actually, I don't see how they can be.

What I am saying is that science has yet to disprove christianity, which you dismiss as being false.

I'm further saying that science *can't* answer the question that has plagued man throughout recorded history: how and why we are here. Science (and by "science" I mean we, people) can't answer it because the problem is paradoxical and currently contradicts our natural logic and understanding.

Christianity *does* answer the question: there's a higher being that exists beyond our own understanding. Perhaps one day we will understand that being and then it'll become science.

Whether or not you care about how or why we exist doesn't make the question irrelevant. Most people do care, even those who aren't scientists.
