If everything has a purpose then evil doesn't exist

[Mister Agenda]

Here's an idea - try taking scientific knowledge at face value, and see where that takes your philosophy.  Assuming that an ancient writing is literally and factually correct, and bending your world-view to it, is unlikely to lead to truth.

will do... doing... doing... done.. All scientific knowledge taken at face value, Now what?

More like taken provisionally, barring evidence that requires it to be updated. The only advantage science has over knowledge from traditional sources is that it is constantly being tested against reality, and only what works is kept; which is why scientific knowledge only grows. Science is an endeavor, and we constantly discover new things. And when it's wrong, that is also discovered by means of scientific inquiry. Science isn't our only source of knowledge; but it's our most certain, a fact isn't a scientific fact unless it's verifiable.

So taking scientific knowledge provisionally as the most accurate knowlege about reality available to us; whatever else you believe should not contradict scientific knowledge. If it does and you're actually correct and science is wrong, it's a stopped clock is right twice a day (by coincidence) situation.
