I am not aware of even a single instance where a single pair of humans with no technological support successfully reproduced (by which I mean: raised a child until it was old enough to survive independently. Just having a baby doesn't count.) If you know of such a case, please give me a reference.
What are you talking about? You are completely out of touch with reality. Society is great and is humans natural state... the vast majority of people are going to eventually experience psychological issues due to being alone and will lose the will to live. However being able to successfully hunt and gather enough sustenance to survive without a larger group, is not particularly 'impossible'...
It's not enough to hunt and gather and survive. You have to be able to reproduce. And you have to do it without any tools or clothing or shelter that was produced by civilization. That is very, very hard. It might not be impossible, but AFAIK it has never been done.
And a community of other humans.
