Re: "Cannot be traced back to the source"
life is common in the universe, intelligence not so much. there's fungus... and that's pretty much it. fungus colonized the earth with meteors billions of years ago and is the main biomass on the planet today. our ancestors walked the mushroom dotted plains of africa hundreds of thousands of years ago and first ate the fruit(fungus) of knowledge which gave us some basic abilities in "imagine something novel and make it real". ever since weve been building/becoming a "better hammer" than random (?) meteors for further colonization. we are basically one of their recent experiments in monkey breeding. i hope they are happy with us so far and decide to keep us. *>D
