How do you know that a large body of evidence is not possible for creationism, Steve.? Have you actually looked ?    The truth is we all have the same evidence , it is the interpretation that makes the difference. The claim that the body of evidence supports one belief or the other is meaningless.    The crucial thing is ....can you substantiate what you say is true/validated by the evidence.    And as theists admit the limits of demonstrating a belief whereas you ,and your fellow atheists claim the intellectual high ground, it is more incumbent on you,s to demonstrate that you really do set the bar high......when it comes to your biased view.   I won't hold my breath !.
