Talking to my Christians friends and family is like talking to a child.
You talking trigonometry and they speaking basic math.
OK 2+2=4, but 70 years for man today can not = 900 years old man 6000 years ago.
Their answer, yes man lived that long, he was perfect. Oh hell I give up....
So I try to show the contradiction in their bible, a story most Christians know..
Try telling them Adam wasn't the first man, they look at you like you have lost your mind.
