I think STANTON FRIEDMAN’S analysis of the Majestic docs is the best.
His website is:
HTTP://WWW.STANTONFRIEDMAN.COM
“Friedman has characterized the kinds of evidence, scientific and otherwise, that he considers to be relevant, which include evidence such as credible”.... source wikiapedia for what its worth which in itself is questionable)
...testimony (what people say)
...analyses of documents (what people write)
...video and physical trace evidence (what people film)
...multiple sources of mutually corroborating evidence of one or more kind. (what people say,..write..,..film)
Though these may be impressive to research and look at to those who believe there are aliens....still no one has presented an alien. They simply are not there.
That link to SF’s page is greatly appreciated. You do your home work quite thoroughly.
