How can aliens exist if NASA opened up the space industry to the public?

I believe NASA is, and has always been, a front for the "militarization" of space... their original purpose is past, and they are not in full charge of the "gateway" to space anymore, but this,... I venture, was forseen by TPTB...

NASA has always been a military tool, just with civilian wrappings...they are a pressure valve for soft disclosure...
