Considering how massive the Earth is, as well as how devestated the landscape is after impact, I'd say people are pretty scatted across the world. Different people in different locations would have had a little less than 300 years to developed potentially anything, including the use of Senjutsu. Its not like everyone left on the planet is within a 50 mile diameter circle, fighting to survive, they are all over the Earth.

Its not a big deal, but for everything presented so far, I have been able to counter with the manga and simple logic. And I'm sure I'm not the only one seeking answers to various questions, but for something to work, it has to make sense to people you are presenting it to.
