Lewis: Do you want some peanut butter sandwiches?
Fay: Thanks. But I'm allergic to foods such as peanuts, milk and eggs.
Lewis: That's a shame. Then there are a lot of foods you can't eat.
Fay: That's right. Hopefully, U.S. scientists will develop "allergy-free" peanuts in the future -- they can genetically modify peanuts to remove the ingredients know to cause allergy.
Lewis: Hmm. Honestly, I don't like the idea of scientists playing god by genetically modifying or cloning something.
Fay: I don't like it either. But I will be glad to see "allergy-free" peanuts!

解析：play god == to make decisions that seriously affect people's lives (扮演上帝)
