So where did the life come from in the first place?

[Junior]

That's a question for the biogenics folks. Did it arrive here aboard a comet or asteroid? Did it arise from the evolution of ever more complicated self-replicating molecules (of which there are many)? Or did God zap the first organism into existence billions of years ago? There is very little evidence extent from the period on Earth when the first life came into being, and researchers are reduced to replicating early conditions in the laboratory to test out any number of hypotheses. In other words, your guess is as good as mine.
