I think if this was alien, the governments would have confiscated it. They would do this due to possible biological hazard risks. All we need is a alien virus pandemic. I would like to see the DNA analysis from a certified forensic laboratory. I do believe there are other life forms in the universe however. And I have seen convincing evidence to confirm this belief. Thanks for posting this.
I saw this too, very interesting, and who knows, totally possible. That area had to have some purpose and with the massive figures they made in the desert, and the landing strip like areas they built, it seems clear that these sites were to be used from the air.
