I was rememebing some sci-fi fic (whose title cannot remembr) dealing with terraformating planest, and it made me think on the possible effects of a civilization on such a place.
This is more related to the future (or even ASB) forums, but I dediced to extrapolate to Earth. Lets claim, for the sake of argument, our planet was terraformed, say 40,000 years ago. Space faring humans from the true home planet, Roswell Greys, Vorlons, Preservers, ASBs, whatever.
Even with our current understanding of science, it is not impossible to guess at a full planetary terraformation: Water from the Oort cloud would give the seas and oxigen atmosphere, and then it's just some centuries of seeding, first algae, lichen and insects, then up to the to full biological chain. Add one or several human groups (either abducted slaves or luddite volunteers) abandoned in the wilderness; a handful of generations and the origins would be completely lost, at best tales of creator gods from the heavens. Human history goes on in schedule: Stone age, Bronce age, China, Roman empire, et all. Until we get to the industrial age.
A terraformation, no matter how good, has several important lacks. The most important one being, the biosphere is a few millenia old. No fossils. No coal, petrol, or natural gas. Would such a planet be able to industrialice? Peat, vegetal coal and plain old wood would cover the lack at the beggining, but they have limits.
Cars (and later planes) would be all but imposible in that planet, not for decades. Trains -first burning wood, then electricity from windmills and dams- would rule the land. Warfare woudl be completely different: No tanks, certainly, and in sea they would have to wait for the discovery of atomic energy to have anything even remoltely equivalent to our modern carriers (useless without planes), or even a WWII dreadnought.
P.D. Another concern, religious/cultural now, who would not be minor. 40,000 years of biosphere. No evolution worth mentioning, no fossil record, in fact any geologic record able to be interpreted will say the planet's life was literally created from nothing 40 millenia ago. The effects this would have on religion are rather evident.
