I have come to understand the people that don't believe in evolution are either incapable of grasping the concept or they are too afraid to accept it b/c of it's (supposed) implications. My grandmother is one of the former. Whenever we discuss it she always asks why apes are still here if we descended from them. I try to explain about a common ancestor, etc. But it is useless. Perhaps she too just doesn't want to accept the implications, but I have to consider it possible she simply is incapable of grasping the theory. My mother on the other hand is of the later group. It took quite a bit of effort but I think she finally understood the basic idea. However, she is simply too afraid that believing it might mean there is no such place as Heaven. And that, she just cannot bare to accept. So it is useless really to argue the facts of Evolution vs Creationism. It's the wrong argument. If the person is capable of scientific thinking at all, you still have deal the emotional question of death.
