"What happened can never be determined with any accuracy so it is all a waste of time..."

Postmodernist nonsense. We can most certainly determine what happened with a great deal of accuracy.

"Yet humanists cannot admit that science cannot provide answers to everything."

That would be Creationists can't admit the Bible can't provide answers to everything. Scientists are well aware of the limits of knowledge.

"They can never admit, for example, that any cause of evolutionary change is unknown or unknowable. "

Why admit to something that is false?

Since science can has an answer for everything, tell me: what is life?
