Oh please! You mean there is a flaw in God's design?
I don't think so!
Why would you assume it's a flaw? Do you think God's design is fully understandable by man?
Is the fact that we grow old a flaw in God's design? Is our susceptibility to cancer a flaw?
Come to think of it, yeah, those are flaws if we are supposed to be perfect. but we are not supposed to be perfect.
