DISCLAIMER: The following statements are a theory and are not to be taken as anything else.
The sage of six paths was corrupted by the Juubi and did create ninjutsu, I believe.
His brother created ninshuu and was the father of the first Hyuuga and Uzumaki(light)
My reasoning is very simple. Both Hyuuga and Uzumaki don't use signs for their techniques. Signs are ninjutsu. Both their techniques are to counter or to restrain jutsu's.
Both the senju and Uchiha carry the corrupted ways of animating nature, relying on other sources. Uchiha's can alter you perception and reality and the Senju animate nature(mokuton) (edo) (space-time).
Besides that.. I can't believe the sage was unable to stop his sons from warring... what? He was an innocent bystander?
Ashura got help from the other brother(uzumaki/hyuuga) and they helped him seal bijuu/chakra in him to fight against their brothers. Ashura relied on the his good uncle and that's why he incarnated back into an uzumaki and not a senju.
The other brother knew what needs to be done. Give the chakra back to the tree.
