Comment A Couple Questions (Score 1) 246
I have a few questions and perhaps one of the more enlightened slashdotters can help me out.
If the Earth was really hit with a Mars sized object that eventually became our moon, does that put the earth "behind" other earth like planets in the amount of time it would have taken the earth to restabilize and have the right conditions for life? In other words, if the Earth was never hit by the Mars sized object and conditions for life were still present, would the Earth have developed life millions if not billions of years sooner? So there is a chance could be millions of years behind other extraterrestrial civilizations.
My other question: If we assume the earth was hit by a Mars sized object, giving our oceans tides and our mantel stability, and if we also assume that the these factors speed up the evolutionary process, is it possible that we could be much more advanced than other alien civilizations?(assuming we all started at the same time). They could still be working on crawling out of the water.
Scary thought either way.
