This video, http://www.bighistoryproject.com/, is worth watching as David Christian attempts to give a timeline of history from the big bang origin.
I am not sure if I agree with all his comments, but it does put really long term history into a context, and notes some key “tipping points” in the lead up to the existence of people.
Unfortunately, he doesn’t attempt to answer the question of “what was there before the big bang?” and why did this happen anyway? (if it did!). But within the parameters of history he has chosen it’s a well presented talk.
