It really is. Reductionist-style scientific method doesn't explain everything right now?! Why then, we must invent something else!
This is a standard human tendency. We both want to believe in our specialness, and in a fundamental purpose. But there is no evidence of either. None. A *scientist* accepts that as the "truth", to be continually tested, of course. Until disproven, the best guess supported by the evidence is taken to be our approximation of reality, and operated upon. It's really just that simple.
