as per christianity, jesus was there in kashmir, india between the age of 18 - 30 years.who said there is similarities?what proofs you are talking about?we still not even know what exactly the jesus story is.many people have cooked up many stories after they started their religion.all the these stories to convert the people.is bhagadvadgeetha,or bhaagavatham or maha bharat or bible is saying jesus iand krishna are same??these the only books we can take for reference.12 years to 33 years where was jesus the whole story was not there in bible.he was only a person bro.after his dead his followers made him god for their selfish reasons.infact one of his follower surrended him to the romans just for 20 silver coins.
there was a tomb in kashmir which clearly said that jesus was died here.
personal opinon - i do not believe but i have read it.
