For years there were accounts of alien encounters where the aliens showed a little black box to humans. The aliens held up the box and pointed to it, then returned to their spacecraft and left.
People having such encounters wondered why the aliens did not try to communicate with them further. The contents in the little black box remained a mystery for decades. Thanks to investigators such as Budd Hopkins and Dave Jacobs, we now know what is in the box.
The box contains a live fetus of a hybrid which is part human and part alien. Showing the box is an act of triumph. The aliens plan to colonize the earth with their new race and replace the human race. By showing the box the aliens are demonstrating that they have succeeded in creating a replacement for the human race.
After aliens take either sperm or eggs from humans, depending on their sex, or in some cases, an alien/hybrid baby, the human abductees are taken into large rooms in the alien's spacecraft containing alien/hybrid fetuses in tanks at different stages of development.
During an abduction, after aliens take either sperm or eggs from humans, depending on their sex, or in some cases, after showing the abductee an alien/hybrid baby, the human abductees are taken into large rooms in the alien’s spacecraft containing alien/hybrid fetuses in clear tanks at different stages of development as shown in the above drawing made by an abductee.
Abductees wondered why they did this. The answer is now obvious, the aliens are showing humans their replacement. The aliens are in effect telling abductees that the new alien/hybrids will replace them. There will be no more humans on the earth.
There is one catch to this situation which the aliens do not realize: some of the fetuses are autistic. The aliens are incompetent scientists and can’t quite do what they are trying to do, so they continuously make trial and error attempts for their new creations, thus causing the epidemic of autism.
