I shall stick to this theory and willing to debate with anyone over it, but before I state my theory allow me to first state who Tobi is. ~
Tobi is a liar, he's been caught lying about his name and identity. The reason of this has been suspected to gather everyone in a single place, he has also lied about the Uchiha Clan massacre. Never gave the full scoop on the whole thing, besides the lying he created Zetsu. A creation made of Hashirama DNA, along with Tobi having Zetsu substance within his body. Furthermore Tobi has been seen using Time-Space jutsu, and hasn't deactivated sharingan since he's been seen using it. Now who else hasn't ever been seen deactivating sharingan when eyes are open? Kakashi. And how come? Because his sharingan is a implant, and the only way to deactivate implant is to close your eyes. So we got Tobi a unknown man with sharingan which is possibly a implant, a liar, and knows allot of things about Konohagakure and especially Madara Uchiha, and even Rinnegan, and Juubi, and Rikudo, and his son's, and Bijuu.
So what do we know about Hashirama? We know he was said to be the strongest shinobi in his generation, furthermore it was said he fought Madara many times. Showed Madara respect and along with other Uchiha he fought, masterful medical ninja and creator of many Hidden Jutsu within Konohagakure. And brother to Tobirama who created a powerful jutsu of own; Edo Tensei, and even a legendary Time-Space jutsu we've yet to seen. Furthermore we've also noticed that Hashirama DNA seems to regenerate on people it's implanted too, just like Orochimaru's except his goes as far as to grow a face. His Wood Release is strong it still exist up until is death, and has the ability to remove bijuu chakra outta people. Furthermore he's highly praised and loved by Konoha shinobi, and teacher of Hiruzen Saurtobi; God of Uchiha. Also defeated every single Bijuu, and gave them to each village of the 5 Great Nations.
So now you know something about Tobi and Hashirama, you're wondering where the connections? Both of these guys are complete opposites, and show no form of relations-on the surface. Where did Tobi get the DNA of Hashirama? Where did Tobi get the sudden knowledge of Madara? Where did Tobi get the sudden knowledge of Bijuu, Rikudo, and Juubi? Speculations of Tobi being Kagmai, Obito, and even Fugaku. All 3 Uchiha yet don't seem to fit the high caliber of Hashirama or Tobi, we've been all thinking Tobi is Uchiha, an evil and known Uchiha. But guess what? We've never seen a Uchiha do anything evil, we've never seen Uchiha born with the Curse of Hatred. Nor has anything proven Tobi is in fact a Uchiha. Madara Uchiha was never evil in my opinion, he's always loved Uchiha Clan and even Konohagakure. He rebel because he stated Senju would oppress the Uchiha Clan and make them dogs, the very clan he loves so much.
Say if you see your family is falling into a trap, your so called family says you're lying and turns their back on you. What would you do? Leave. So Madara left and said "screw it" cared to much for his family and village, returned with Kurama to fight Hashirama and save his family. He went as far as to hate every single Senju, why? Because he looked at them as evil monsters who was manipulating everyone, so he fights Hashirama gets defeated. After his defeat no speaks against the Senju for awhile, and Konohagakure no Sato is considered "peaceful". But wait! The Uchiha Clan finally realizes what the Police Force was all about, Konohagakure didn't trust them and were keeping tabs on them. The Uchiha Clan figured out what was going on, curious as to why they were being watched they sent Itachi.
The Uchiha Clan suspect what Madara said was true, and they needed to get out the situation were in. Nothing about being enslaved and wanting to break free is evil, is it? So far what I said about Uchiha Clan is from the Uchiha Clan perspective, a family of shinobi whom just want to be treated as equals. They signed the treaty because they wanted no more wars, only wanting to live in peace. So the Uchiha's are planning a coupe, wanting to overthrow the government and place a Uchiha as Hokage(assumption). But Hiruzen; Sarutobi, wanted to end things peacefully. But Danzou and the elders(Clans are unknown) want to kill the Uchiha, but why? To avoid the destruction of Konohagakure.. xD
::Contradictions::
They believe Uchiha were the reason of Kurama attacking the village, and causing the death of Minato. And for some reason the Uchiha were no where to be seen, during the attack of Konohagakure. If anyone saw the anime episode of Kurama attacking the village, you would know that would've been perfect time to strike. The fact they didn't strike means Danzou and elders were making excuses, and are a bunch of liars.
::End::
So back at the Valley of the End Hashirama defeats Madara, and gives Madara his DNA just before he dies. And states he'll be revived by a boy named Nagato, and tells Madara the secrets to Rinnegan and the world. Madara passes away and Hashirama walks off a hero, and beloved.
Now some where along the line Hashirama was on his death bed, and was about to die. But he performed some sort of Wood Style jutsu, therefore reborn himself from one of his trees. We've all notices that a giant gave birth to the clone of Army Zetsu from bijuu chakra? What if he did a similar jutsu on himself. Chakra is a product of physical energy and spiritual energy, every single tree he has made comes from his chakra. His Physical energy is immortal, it lives and grow. His spiritual energy is all across the village of Konohagakure, so part of his subconscious mind flows through Konohagakure. Some he comes back alive weaker then before, similar to Zetsu power level but much stronger. The part of him that died was revived by Orochimaru and sealed off by Hiruzen, everyone assumes he's dead but he still walks.

Question: Who in the world would say so much information about Uchiha Clan, but so little information about the Senju Clan?
1st Answer: Hashirama Senju
We've seen Madara Uchiha is dead, the only person whose stronger then Madara Uchiha is Hashirama Senju. The only person who could have so much of Hashirama Senju DNA is Hashirama Senju, the only person who could have so many sharingans in a little in some hidden laboratory is Hashirama Senju. Madara loves Uchiha Clan and would never collect so many eyes, Tobi even states Hashirama never stolen his brothers eyes but were given to him. Uchiha Clan have been claimed evil and demonic, but have only been shown to be abused and victims of Senju Clan and Konohagakure.
