Oh goodness….
I can believe aliens are possible. Not likely to exist in any intractable way as they are before or after us in their evolution or just too far away to know we exist.
A radically near miss with another intelligent species could be 100 million years when dealing with the age of the universe.
The whole reptile aliens here on earth, living in the mountains or oceans or better yet hollow earth, with left over Nazis is just a bit much to even consider pondering.
The Catholics can't even get ye basics done. They are not holding super secret info of ANY kind.
That said…I'll probably still give it a watch if it's done in an entertaining format.
