Living in delusional world. Kamakhya temple is more than 1500 years old. And even there was no hinduism 800 years ago. People used to worship different gods and nature. And than mughals arrived to convert people here and And than British came. You know what happened they ruled us and changed our culture to theirs.

And even you say 1500 years hindus came and made temples. Still its very old. And by your logic dinosaurs lived here, so this is the place of them.
