NASA is probably run by aliens. I am dead serious, mostly.
I think NASA has found something more significant than a "microbe". Anomalous artifacts on the moon, the "face" on Mars, extensive footage of UFO's, Martian probes inexplicably losing contact. No, I don't believe the moon landings were a hoax. I consider myself a "realist," not a "conspiracy theorist." NASA's actions over the years have been suspicious and non-sensical as are most other "coverups." Stuff just doesn't add up or make sense.
I agree with Numina. Like I said, they're giving us "scraps" when they've got the 5-star dinner in a vault somewhere marked "top secret." What's most disturbing is the amount of taxpayer money being used in the space programs and yet they're not sharing the wealth while millions on Earth starve and live in poverty. NASA is also so wrapped up in contracts and big business that it's actually corporations controlling the information. If you think NASA is all about honest science with no hidden agenda then believe what you want.
