Can someone tell me if what I wrote is good...?

I think it is excellent, but it seems that you may be a bit biased in favor of the one denying the existence of a higher being- but it may only seem that way because I'm only reading a small excerpt of what seems to be a much longer dialogue. I only say that it seems a bit biased because his argument seems to be the most prominent. I'm reading more of his reasoning for the nonexistence of a god than I am of the argument of the other in favor of the existence of a god. Otherwise, I really rather like it.
