"I actually kind of doubt the present scientific theories about the origins of human life on this planet are correct." etc..etc...

Well, you are no doubt correct, LH...at least about the details. That is what theory and scientific inquiry are about: constant adding to and correcting of ideas. But I see no indication that the basic notions about origins and evolution are in any danger- barring some totally amzing new discovery.(you know...an alien ship buried in Atlantis with unopened containers of DNA labeled "open in 7 million years")

Right now it just a matter of honing in on dates, places, specific order and failed lines. *IF* the carbon dating process is not shown to be flawed and no outright tricks like Piltdown Man are discovered, this current 'general' theory looks like it will just be refined.
