Here is a NASA video of a panel discussion of early conditions on Earth and how these inform the search for habitable exoplanets:
During an August 20 event at NASA headquarters, called Ancient Earth, Alien Earths, a panel of scientists from NASA and other organizations discussed how vastly different and inhospitable we all would find ancient Earth, if we could go back in time.

We have acquired a unique record of interviews, speeches and presentations over the past three-plus years. This project is seeking funds to transcribe our 102+ hours of video content for donation to the National Air & Space Museum. It will take $10,500 to get the archive transcribed and into a repository at the Smithsonian. Our stretch goal (anything above $10.5K) will enable us to continue documenting the broad canvas that is the NewSpace community.
