Not knowing the answer to a question is not a valid excuse for making up a fairytale to explain it.
An all-loving god would surely not damn his children to an eternity of torture simply for being born into a culture that believes in the wrong deity, follows the wrong holy book or attends the wrong type of church services.
There is no evidence to suggest that God helps people. There is, however, ample evidence that people can help themselves and each other.
Scriptures may have grains of historical truth within them, but there is also ample hyperbole, speculation and mythology.
Close analysis of ‘miracles’ have never led to any proof for a supernatural explanation, and, in fact, many have proven to be cheap magic tricks, hallucinations or primitive misunderstandings of natural phenomena.
If God creates morality, then morality is nothing more than the whimsy of a divine being blindly followed by humans.
It is likely that religious beliefs have been so widespread because they tap into the psychological desires of many people, not because there is any external proof of their veracity.
Science doesn't claim to have absolute certainty about the world; it creates models that provide the best explanation based on the available evidence. If additional evidence is found, the model can be changed.
An unknown cause is not the same as divine intervention.
