what is this? full of rubbish story and noob idea vishnu is anient "adi narayana" Christian civilization just came in 2000 year before but narayana is creater of every thing including brahma and shiva and universe
when u consider about greek they talk about only theyvargal indra ,varna and mdharmaraj
if u no about hinduism then talk other wise dont interfer in it
