It appears that the only meat in your OP is to discuss macroevolution.
If that is what you wish to discuss I suggest:
1) Review topics where this has been discussed before. You may use the internal search tool to find them. You may also use Google but use the advanced search and restrict the search to this site. It may be that you can simply add to the existing topics.
2) If you wish to discuss macroevolution then a better title might be: MacroEvolution -- evidence against or something like that.
3) If that is what you wish to discuss a goood opening post would define what you mean by macroevolution (this is both because the orginal use in biology has been shown to occur and because different people and groups who disagree with it define it in many different ways).
4) You might then give a few quick points that you believe show that it can't and has not occured. There would be no need to defend all these with evidence until you are asked to do so. But rest assured you will be asked.
