I'm not religious, but for the sake of the argument, riddle me this:
I am God
I have no concept of good and evil - this is something you came up with. I work with right and wrong - something one can measure. Then again, your Earthly lives are just a fraction of a my second - so your perspective on time and the causal effect is quite limited. No wonder it took you thousands of years to understand it might not be the best idea to slap your kid or hold him off every time he is about to fall. Welcome to the concepts of time and learning.
I gave you free will, isn't this what you wanted? It implies the freedom to be a mortal moron. If I wanted a creature that would make no mistakes, always listen to me, and be virtually indestructible... well, I'd just get another angel, or a dog. Don't ask me why I made you like that - I do remember giving you a brain also. With great power comes great responsibility :), time to figure it out my son.
I have a gazillion of 'children'. All living creatures are my children, and there's even more in the next life, you know. Oh, you don't know.... well, believe me, there are. When you grow up and are ready I'll take you there. What happens before that is just your childhood, so yeah, there'll be some falling - that's how you grow up.
What you refer to as suffering caused by some evil is actually nothing more than the result of what you and my other children are doing.
Yeah, the bible is not 100% accurate, but it's the best you've got. Try asking a 6-year-old to explain your world view to a 4-year old and you'll know what I mean. Just as any first-grader you'll have to simply memorize some basics at the beginning. Btw, if you had followed the dietary instructions you wouldn't have gotten so fat.
P.S. It's not my fault you decided to dogmatize everything and forget the basic nature of creation and life - it's based on movement and change. So, please, don't ask me about good and evil or why I made you like that - I do remember giving you a brain also. With great power comes great responsibility :)
