OpenMaw- the ancient astronaut theory actually isn't as implausible as you seem to think, it doesn't "fly in the face of evolution" in anyway (which the theory evolution itself still has it's kinks to work out) because beings evolve and adapt according to their environment, if there is no need to evolve, if they are not forced to evolve, they will not. Yes we understand the basic gist of how things got started on earth and with mankind, but theyre all just theories at the end of the day (which btw I suscribe to) based off what modern man has deduced from evidence we've found, but in no way does that actual evidence preclude the possibility of alien interference, obviously throughout the ages we have changed our ideas of how everything started based on new evidence and if you think that won't continue to happen you're kidding yourself. We know a lot, but not nearly everything. The human race essentially rules the earth, and we are one of many, many species on the planet, no other species before or after us has reached our level of cognition, we speculate dolphins are as smart as us based on the size of their brains, but if you've seen a dolphin in action-you know that's not the case. What makes us humans as a species so damn special? Why are there so many correlations between religions? Both past and present? Why have we had a concept of "god" since our inception? You can speculate why, but you don't know, because nobody really does.
