Atheistically
Not all YEC Christians believe the exact same thing, but what makes them YECs is that they all believe the Earth was created 6 to 10 thousand years ago with all life forms being created in their present form. But not all Christians are YECs and not all Muslims are YECs. The fact that there are Sunni, Sufi, Kharijite, Ahmadiyya, and Shia Muslims, along with various sub groups and even more sects than those proves that not all Muslims believe the same things.
So you admit YEC are fanatics?
