The Nephilim and the Conquests of Joshua

Jimmy Akin would be a very interesting guest for any religious discussion, especially about these matters. Trevor Lynch says the Nephilim are spoken about and alluded to all over the Bible. That's what the conquests of Joshua was about, clearing the Raffagne giant Nephilim clans from the land. Also, one Peter and Jude is referenced. I wonder if they were the Denisovans.
