@nothingplanet Thank you for asking me. I just read the discussion and I don't think I can contribute anything more; you have provided enough rational arguments. Moreover, biology is really not the area of my expertise. Maybe @arteteco can help.

No, argument was fine as far as I can tell, but in my experience in arguing with creationists just use it as a way to refresh your biology and geology notions, don't let them get under your skin =D
