An ability the Sage of the Six Paths had, referred to as "Creation of All Things" (万物創造, Banbutsu Sōzō). The process he used is explained to have initially involved the administration of imagination, and the spiritual energy which forms the basis of Yin chakra to create shape and form from nothingness. It is also said that the technique Izanagi is based on this technique.

The Sage was said to have created materials from nothing using Izanagi.
Izanagi was used with the Danzou vs Sasuke fight, but it permanently closes the eye sharingan after it has been used.

If it does close the eye for good, why didn't the Sage's eyes close? What if the Rinnegan made it so he could use Izanagi without his eye closing?
Madara acquired the Rinnegan during his final fight with the First Hokage when he aquired his DNA. He is the only known person to acquire the eyes by developing his eyes beyond EMS.
The stone tablet belonging to the So6p - I think the secret to this was passed down by the sage's older son, secretly to the Uchiha as he was bitter about not becoming his father's successor. His dojutsu, whether it is the rinnegan or a slight variation, should've been able to read the tablet because he directly inherited the Sage's eyes. The early ancestors of the Uchiha clan learned top secret details about how combining Senju and Uchiha DNA resulted in the formation of the Rinnegan. Many Uchiha leaders may've tried in vain to gain Senju's DNA but they were defeated everytime.
Until Madara finally obtained some, albeit losing to Hashirama in the process.
Now for the interesting part:
Tobi is an Izanagi creation, made by Madara in his last moments so he could be later revived to finish his work. He is part Zetsu, the Zetsu part making up his inanimate body. Tobi describes himself as being a 'shadow of his former self', possibly explained by the fact Madara was in such a weakened state when he created him and over time, as his master was dead, his power waned.
I believe Madara couldn't use Izanagi to prevent his death as I believe it's not simply a 'one off' technique; eventually he would need to re-use Izanagi to save himself from being gripped by death once again and I don't believe he had the required strength to keep this going; he had life threatening injuries and was too weak to put this kind of cycle in place.
I think only the So6p was strong enough to use it as a one off technique; which is why when danzo or Tobi use Izanagi they don't remain 'invincible for a long time'; the process must be repeated everytime a new attack hits them.
But before he passed away he had to find out a way for himself to be revived. He was severly wounded from his fight with Hashirama after all. Tobi probably didn't have enough chakra to use the rinnegan at that time, because Madara used up the little Hasirama DNA he had.
Madara felt it was more efficient to be brought back using rinne tensei at full power, full health and under no-ones control (unlike edo tensei). So Tobi was necessary in order to keep the plan in motion and ensure Nagato did his duty whilst Madara was dead.
1. So they scout for possible candidates to host Madara's rinnegan so that he could be revived using rinne tensei.
This person must have high chakra (Nagato, being Uzumaki and everyhting) because the rinnegan uses up so much of it.
2. No-one affiliated with Konoha, once again Nagato so that he would be willing to go through with the plan. Moreover he would be easily persuaded and I would even bet that Madara or Tobi had something to do with those Konoha ninja's killing Nagato's parents.
After all:
Tobi says 'he is nobody'; Have you ever thought he was actually telling the truth?
Nagato betray's Tobi using rinne tensei on Konoha when it was supposed to be used 'for his purposes'.....etc.
The main point here is that I believe Tobi is an Izanagi creation with a white zetsu body. He is devoted to his master, claiming to be no-one and only interested in the completion of the moon's eye plan. I also think being created using Izanagi, Madara created Tobi's memories and personality, possibly the reason Tobi knows so much is because these are Madara's memories, Madara's emotions.
Quote from Tobi
"Legend has it that Uchiha Madara was bested by Senju Hashirama...but is the legend true? The true winner is he who chose to focus on the future" = Obtaining the rinnegan and subsequently the completion of Moon's eye plan.
Anyways, what do you guys think?
