There are plenty of things we will never know and that there is no way of ever knowing. Here's some. Given this 10k year old pot https://factsanddetails.com/media/2/20120207-JomonPottery.JPG https://factsanddetails.com/media/2/20120207-JomonPottery.JP... What is the name of the person that created this pot, What day did they create it? Were they in a relationship at that time? Did they have children? How many siblings did they have? There's no way to know. You can theorise time travel to find out or you can weasle into believing we'll somehow make machines in the future that can measure every facet of every atom related to the creation of the pot in such a way as to be able to trace their trajectories through time backward but both of those are grasping at straws, things that are unlikely to ever actually come to pass. The reality is we'll never know the answers to those questions. The same is true of how the universe began. The best we can do is follow our theories of how the universe works backward and see where they lead and then try to create those initial conditions and see if we get the results we expect. It may be impossible to create those initial conditions though and even so, we'd be guessing at what those initial conditions actually were as we'd be assuming that running our calculations in reverse is true describe the actual initial conditions whereas they really only describe assumed initial conditions.
