SC... some people see everything around them as proof of god (or a god)
you believe (without seeing it), i imagine...that there was some big bang or some other scientific explaination for the creation of what is around them.
others, while they might believe there is some scientific explainiation for the creation of all that is around them - also believe there is a higher power (god) that had a hand in it all too.
it's all a choice in what you consider to be "proof"
