Hi teacher!
Well, I don't know who this Dennis is but I know where the poem he wrote down came from.
It's called Antigonish and it was written in 1899 by Hughes Mearns.
You can find an analysis of this poem here: http://debate.org.uk/topics/apolog/godexist.htm
It's a little hard to understand but the first paragraph is interesting.
well, that's all
Lou
