If there were proof, there would be no need for faith...ie a blind belief that such a divine being exists. Every last one of us would be pouring into churches, mosques, synagogues, temples and whatnot and obeying every last rule such institutions apply. Since we're not doing any such thing, that's pretty good evidence that no such proof exists.
Faith should not be blind, it should be informed. Also don't bother going to any 'institute that has lots of rules, there is only one rule, which Jesus gave, that is 'love one another as I have loved you'. A bit difficult, unless you are really ready to surrender your life altogether for some one else.
Faith is, by definition, 'blind'...ie something is believed despite a total absence of what non-believers would consider to be acceptable 'evidence' that it is true.
And surely the Bible has something referred to as "the Ten Commandments", as well as any instruction Jesus supposedly issued. If that doesn't qualify as "lots of rules", I'm not sure what would.
There I shall leave it, as discussing this sort of thing with a believer makes as much sense as trying to nail jelly to a wall!
