Where hindu gods like BRAHMA,VISHNU,DURGA,KALI MATA,SHANI DEV,SURYA DEVA,CHANDRA DEVA live? did they exist?

Its mythological as u urself write just like the Greek gods and goddesses. And y limit your questions just for the Hindus to answer. And how many hindus know the vedas. 'Ved' for your information means 'knowledge' and the corpus of human knowledge is ever increasing.
