"i dont see why someone would believe in darwin but not belief in the devil, the devil is real and you can see what evil he reaks on this world everyday."
Various evidence that Darwin exists such as his books, papers, artifacts and even his remains help. The lack of all of the above for your Devil character is detrimental to belief in him.
"the devil makes war and desease and famine and yet you claim darwin made this?"
What sort of fool claims Darwin made any such thing?
"how does darwin explain evil and how it comes to this world?"
Is there a philosopher by the name of Darwin that I'm not aware of? If you mean Charles Darwin of evolution fame then I have no clue why he would have tried to, nor why you think he should, explain such things.
"He cant because he didnt know because the devil is real and darwin isnt."
Oh, well then. That's certainly a convincing argument you've got there, isn't it?
"Satan was proably working through the devil to test the faith of christians well i stand strong behind my faith, its the only real thing darwin is just made up"
What sort of hodge-podge Christian theology are you using? Satan and the Devil are, by the thinking of most Christian sects, one and the same. Of course, when there's nearly forty thousand different brands of Christianity I may have missed one where that's not the case.
