One thing I do say is though, is "MAYBE" aliens helped "BUT" was it really needed or perhaps they were just "hinting" at a better formula type thing. But thats just one of many hypothesis. My strongest belief is that we did it ourselves and that aliens are just studying us like we study animals. (or as I shudder to use this reference but the g/f watches the show religiously) Like the people in Star Trek do too "pre warp" societies....(I think I choked on some vomit saying that.....never agree to watch a show with your g/f on a regular basis if you don't ask what it is first.....)
