Since humans were not alive during this period of time, it is difficult to know for sure what happened and if our predictions are correct. If we are able to understand the Precamrrian Era then we are capiable of identifying if another planet is like ours and being formed the same way our planet was created. Being able to identify this would be a big discovery for humans because then we would know what to look for and know if a new found planet could be suitable to support life one day. </span>
