If someone says science can't explain everything what's the best way to repond?

With a Christian that may be good, but a Muhammadan would start taking about the Arab Golden Ages and how they supposedly invented the scientific method (even though it goes back to ancient Greece and the Arabs merely improved upon what the ancient Greeks have them). It's crazy to think Christianity has become more open to new ideas and the Muhamnadans are less open. It's like they've switched places.

Before the wrath of Muhammadan came the Arab's did invent the scientific method, atleast the modern one.

Then Islam came and fucked shit up.
