So boys and girls, Ladies and Gents. I have this crazy thought. So the earth is what, 4 billion years old? And sure throughout the last i don't know 200-300 million years of that life has existed right. So hear me out, Isn't it possible that before the human race dominated the planet that there was another intelligent race in the ancient past? One capable of most of the things we find possible today with our current understanding of technology and the observable universe? One would think that given enough time between dominant species rising and falling that plate tectonics, asteroid strikes, weathering and erosion much of the detectable evidence of such past intelligent races would be all but impossible to find right? Now i know that all of the nay sayers are going to preach "well what about all of the dinosaur fossils" "surely an intelligent race with advanced technology would appear much longer than bones. Well the odds of finding a fossilized dinosaur bone is 1 in one million. That's not even including finding a complete fossilized skeletal structure of a dinosaur, in which case the odds get slimmer exponentially. So what do you guys think? Are we the first intelligent species to inhabit planet earth or have their been failed civilizations before us on this very planet?
