Hank, get your head out of the sand. It's very clear what my point is:

ME: The government hasn't divulged any information about knowing that any alien lifeform or certainly an alien intelligence has had contact with Earth

YOU: That may be due to the fact that they want to maintain a technological edge.

ME: They could divulge the information on the existence and maintain the edge.

YOU: No they couldn't.

ME: Explain.

YOU: Reread my paragraph.

That's the problem. Explain how presenting evidence for the existence of an alien spacecraft in New Mexico or Nevada would compromise any "reverse-engineering" efforts. You're making up theories without evidence and it's getting tiring.
