Many believers are convinced there is a plan for us, although the plan is way over our heads and above our level of comprehension.
If you believe this, how are you so convinced? If there is nothing to judge this on, why not assume there isn’t planned journey for us all and start looking at what areas that are backed by evidence?
If there is no evidence for something, it doesn’t mean it is true and simply beyond our understanding. It probably means it isn’t true or worthy of believing, especially if a God is supposedly involved. I know that many aspects of our nature is beyond our comprehension, however nature is not able to communicate with us. If nature could speak and still avoided our curious questioning, I would be against it too.
