Scientists can say they don't know...

It is interesting that scientists can claim they don't know and that is ok, while on the other hand a theologian is supposed to know. I gather the claim that he, the theologian, knows God puts a bit of pressure on him to have answers. The theologian however is not God, so the pressure is a bit unfair. God does not provide answers google search style. Yet when the theologian does claim to know, the scientist often replies that he can't possibly, even though the scientist himself doesn't even have a place to start.
