I agree that there are ways to make it even more interesting. But one of the things that never ceases to amaze me is the way that a record of history is often preserved somehow. Whether we are speaking about the universe, whose early history can be observed, for example, in the temperature of the cosmic microwave background radiation, or humans whose history is partly recorded in the details of our genomic sequences, or the Roman Empire, some measure of the economic output of which is apparently preserved in Greenland ice cores. I find this mind blowing.
