god existence is not the must in every religion,
so if you say every religion is wrong , ur the stupidiest person in the world

World renowned Atheists have critisized abraham based religion not hinduism
 ie christian , muslim and jews 

And what is your definition about god?

Sun is god in hinduism and we all know sun exists. 

if people following religion are wrong ,it doesn't mean religion is wrong.

for example , stupid people who were lining up for buddha boy doesn't mean gautam budddha has re incarnated.

And lastly , people learn about real religion truths not what your ignorant parent have thought about it.
