That would certainly seem true, and may very well be the case; however, it is possible that he said it that way to [ultimately] promote the existence of aliens...
I dont think he would lie but if he did we would know because most companies spend millions on research/brainstorming new ideas
Also, I don't believe in aliens
It is also evident that God never wanted us in space. It's not made for man even 1 light years is an unreachable distance. The Milky Way alone is 100,000 lightyears and astronomers have surmised that the universe is 93 billion lightyears.
I also don't believe in government propaganda. the people who believe in Aliens often take it over believing in any religion.
And if there were 'alien" they would be just like us made in God's image. They would be unable to project thoughts or images into the mind. Only God and the demons can do that.
