He's got a point:
Earthquakes, floods, asteroids, volcanos, disease -- all caused by angry gods. Religion 5, science zero.
Earth 6000 years old. Religion 1 science zero.
Earth fixed and cannot move. Religion 1, science zero.
Sun revolves around earth. Religion 1, science zero.
Aw, js, you'se is breaking the rules. In olden times, people were allowed to get angry with their gods if the rain god, for example, did not come through. In modern times, you praise God if you think you got what you wished/prayed for [and especially if your neighbor, brother-in-law or political opponent got what he 'deserved'], but you are not allowed to shake your fist at God when He or She ignores your prayer or when He caused or allowed some huge personal or social disaster.
We have PC now, and gods have to be treated with political correctness. Gods can only do good; and even when bad things happen that is because gods know more than you do, and it is 'really' for good in the overall scheme of things. So, there. It is really very simple. Get on board.
