If aliens aren't real, then why did?

Yes, they found out how to make them crash, and we are using their technology, at least what we can figure out. In one of Preston Nichols books, he describes a captured spacecraft it was 15 foot by 15 foot by 15 foot, but inside an alternate reality, and it was huge. He tells very technical details about the ships and how they work, if you have any knowledge in electronics, you can understand it. Who said there are not aliens? The media, the ones who are forced by threats, lawsuits or bought off with money to tell us what the powers that be want to tell us, true, or false? Have you not figured out by now most of what we hear is lies, like for instance, the illusion that we are not safe anywhere, 911 was behind that, and so we will gladly give up our liberties for a false security, so we can all be more slaves to them than we already are? If your struggling to make ends meet, then you should understand, it is only going to get worse.
