I basically took a historical perspective on the story, and just laid out the
basic events going about a thousand years back, and a thousand years forward in
fair detail, and thumbnailed-out the rest for about a million year period.
I alway figured that Earth would have pretty much the lowest tech level going
in, because that would make it more interesting, and preserve some of the
wonder of SF storytelling...you only get that sense of awe when somebody else
has something you don't.
