^Oh I was giving examples when he brought the giant meteorites from the sky, it was some kind of Rinnegan technique he used Susanoo for that, at that time he was Edo Tensei, now he is not edo tensei he has real body,

My Theory:I think the eyes lay the foundation for chakra pathway system, like our nervous system, the hand seal are for controlling flowing chakra inside body, sometimes if the technique becomes easy the hand seal aren't required to perform the jutsu the user can know the flow of his chakra, so conclusion is the eyes already gave the power to their bodies an and its overuse created the pathway, so this has caused the person to use the technique without eyes, Susanoo only requires Mangekyo Sharingan for both eyes to be Awakened "It is not necessary that the eyes should be present"
