Atheist only: Can you help me to challenge a theologist?

OK folks the story began when I took my English major this year in a university and I’m required to take the religion class,among other necessary classes. Here we go,today I enter my religion class even though I’m an atheist. I thought that I can learn some history fact and culture in that Christianity religion class despite I’m an atheist. From the beginning till the last of this lesson this Mr theologist keep reproaching atheists people and atheism (especially US people since he took US people as an example of ‘bad apple’),he said that no matter how good atheists in their life they’re actually arrogant people since they don’t want to believe in God,he also tried to manipulate other people about real-life science (he said that heaven exist on earth,and in your heart,we just can’t find it since it’s out of our capability to find such place and all of us must answer that way if he gives us such question in his exam. LOL I clearly seen stupidity there),and other negative perspective about atheist people (believe me,you don’t want to know all he said).

I keep silent during the class since I feel that I need to respect his perspective,especially when this is his first time but he keeps flaming atheism and I think I need to give him a ‘lesson’ by challenging him with lots of science debate and question.
So atheist people,can you help me to kick his sorry ass with your brilliant idea so I can win this debate and make this dishonest theologist speechless? I don’t care if he gives me a bad score,so please suggest me a good question or other facts about religion (I would like to take prehistoric remains and evolution theory as my debate material and I hope he’s bright enough since he said he’s a Phd).
