where is your evidence of microbes to man evolution

You don't seem to understand that evolution is not a single line. There are branches, extinctions and dead-ends all over the story. There are also myriad gaps in the record. Evolution is a story of diversification from common ancestry, not a progression from one living form to the next. It really is difficult to discuss this with someone who is rather proud to profess their ignorance of it, and I repeat my oft-made suggestion to you that you get a good book about evolution and have a look. We non-believers were forced to study the Bible after all. At least it would be voluntary in your case.

As for being stumped by creationist questions, well they are usually such dumb questions that they can have the effect of leaving one utterly speechless.
