Alien abductions, Space Force and UFO reality

If humans abducted other humans in the same fashion as aliens abduct humans, it would be a crime and some folks would end up in prison. Also, the new military branch Space Force is discussed. Is one of its purposes to deter alien invaders? Finally, humans are living in two worlds - one world is a fictitious one where there is no extraterrestrial presence on Earth, while the other world in based in reality where there are aliens among us.
