Former Israeli space security chief says ETs exist, and Trump knows about it

This is exactly why we know Ets don't exists. We would've heard him at the very least hint or brag about the information.

For the seriously interested, the book that this guy is promoting is available as an ebook here: https://www.e-vrit.co.il/Product/19584/%D7%94%D7%99%D7%A7%D7...

I don't read Hebrew unfortunately.
