If you "run the clock backwards" using the Friedmann equations, you can avoid a singularity; you just need the pressure and energy to behave in the right way when the Universe was very hot and dense. The catch is that "the right way" in this case means that ρ+3p<0; in other words, either the energy density or the pressure (or both) have to be negative. No conventional forms of matter are known that satisfy this inequality, so unless something really strange was going on in the early Universe, there must have been an initial singularity. (Or, more plausibly, there was a time in the early Universe where the spacetime curvature was sufficiently large that the laws of GR as we know them did not apply.)

Explanation:
There is a possible chance that humans would survive with out plans but they could also not survive without plans. I chose to be on the side where humans wouldn't survive without plans. The reason that they would not be able to survive would be because if they had no plans and most people rely on the plans for surviving that why I think they wouldn't survive.
But on the other hand, if they knew surviving skills or at least had a back up plan if they lost their plans, they would definitely survive. I hope this is the answer your looking for, This knowledge came from my head.
