Why so many religions?

Hello friends , today we are discussing about one very important fact about the world which is, why so many religions in the world?So if you will see carefully world which separated by some mountains or by some big rivers these two sides are unknown to each .Lets take an example , if you will go to Islam originated country  you will find they are lack of vegetables and other stuffs , so they eats animals more , also because of lack of woods they prefer to bury the dead body,
and this become tradition for them.
In the same way if you will come to India , here soil are very fertile because of the rivers and also there are many fruits and other options are available to eats , so the people here eats only these things ,
and this become tradition in India .
So what i am trying to say you that all the religions are developed according to the environment of that places.There are many religions , Like Islam , Buddhism , Christianity , Jainism etc .Many people make a mistake to call Hinduism as a religion . Hinduism is not at all any religion , fundamentally it is a process which is running since long time. Why I am saying this because no one is founder of it like other religions .One more thing is there which is very much responsible for various religions which is temperature , because if you will go to places like desert for example Islamic country , you will see people are hiding there faces and head , it is because of intense heat which can burn the skin . At the same time if you will go to the places like Europe the temperature is cool and no need to hide face from sun , no problem of burning of body.
