you need to think the impact and significance of "replicating every event". that could be the same amount of an iron compound, or a comet crashing with a particular amino acid (some theories to the starting of life in the first place), or the collision of an cosmic ray with a early bacteria...
the number of events to be repeated exactly to reproduce homosapiens is obsurd. its infinty to the power of infinity against. i think its actually outright impossible, as replicating every event wouldnt be possible unless the other planet were in the same place as earth.
