thoughts about god

I can understand that if there exists a god ,there is only a single god, rest all are aliases pointing to the one god.so the question about one or many gods is settled for me.no need to discuss about that.

So , moving on, this is my doubt or view. its about the rules set by the god for us poor souls.
There exists so many different religions on earth. atleast 25 atmost a 100+, all with contradicting theories about what "god likes" and what "god dislikes" (isnt it funny , just thinking what god "likes" and "dislikes")
What makes a hard core believer of one religion think with 100 % certainty that only the set of rules mentiond in his religion's scripture is true and the things mentioned in other religions scripture (which are equally good for men and women) arent favored by the god.
Dont the people believing in other religions have an equal right to believe what they believe is true as well.

As I know no religion has any particular advantage with respect to any kind of proof about what the god actually said.
And if one religion produces one such proof , 3 other religions can produce 4 other such proofs about their (different) religions. there is no point discussing about such "proofs" , it will never end. And moreover if god really wanted to leave a proof , it could have come anyday as leaflets from sky or an open announcement in all languages spoken. It has never happened(or has it)
So isnt it clear as daylight their exists no proof at all about any the authenticity of any religions on earth and that god doesnt take sides.Arent all religions just speculation and hearsay (I know there are people who will have a different opinion on this, I can only pity their ignorance and inability to think for themselves, no offence meant)
what I believe is this , dont waste your time thinking about what god likes and dislikes, god doesnt want you to do that.Instead just wake up in the morning , do your job, help somebody if you can (atleast dont hurt anybody) go to sleep at night, and die someday.
And in between in your life ,if you are praying to god , ask god to give you the ability to think for yourself, not going blindly by some book which you don’t know who has written under what motive

whats most funny about it is that even after thousands of years of the hardest , the most painful lessons , even the most literate, intelligent people dont seem to understand that blind belief does more harm than good, instead they continue to argue and teach others about "what god said" .
God must be ROFL thinking how stupid we are
