The last few crumbs have certainly caught my fancy but perhaps we are misinterpreting them. Classified space programs have probably been going on ever since German technology was imported to the US after WW2. The 'aliens' we think of may be just fellow Earth dwellers who suffered prolonged exposure to cosmic conditions and fell ill. If there were actual extraterrestrial life forms why wouldn't they take over this planet and harvest its resources for one?
If there are any to begin with. Most 'aliens' I have seen in various photos look humanoid to me. Could it be that space is that harmful to humans? It's well known that muscle mass lessens and bones become brittle the longer you stay in space.
What brand of Christianity is yours? I'm talking science and here you are coming at me with Satan and demons. FFS.
