Those are all questions. Not even hypothesis.
One should doubt about those kind of questions even more because they are human-centric, that is they are made to put the human in the center of it all "there shall be a reason for the human, etc", and those questions are being postulated by humans, so the -possible- source of bias is quite clear.
It would be great, from the human-centric point of view, that humans and everything around them have a purpose, it is such a convenient thing for humans if it is like that, that if humans postulate it you should be very skeptic about it (due to probable bias).
Again, it is not impossible, but without a proof it is as possible as the contrary, that is "no purpose, no reason, all chaotic". Faith is cool, but it is not a fact.
