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

I didn't say science can answer everything. Please reread what I said.

"They can never admit, for example, that any cause of evolutionary change is unknown or unknowable. "
Why admit to something that is false?

That is exactly what you are saying. If science cannot answer something it is because it is not knowable for some reason. If course, science can speculate endlessly but I don't consider that type of "science" to be worthy of the credibility we rightfully give to the hard sciences.
