The very concept of printing organs is mind-blowing and probably the closest thing man will ever come to creating a miracle. The usefulness of such technology can be life saving for organ replacement (without rejection) and eliminate the need for donation. For burn victims it can mean the difference between life and death as well as reducing (if not eliminating) disfiguring scars. The same can be said for replacing lost limbs. The use is near limitless.
But caution must be exercised as the mind of man can conceive of great evil as well.
Many do not believe ‘little grays’ are visiting this planet and involved in abductions of people, for whatever purposes. But here is a bit of grist for that mill: all indications point to these gray near-idiot worker bees as having been ‘printed’ such that they are all alike. And whomever printed them has programmed them to have about an 80 IQ ... they often get peoples’ clothes on backwards or inside out when returning them from an abduction, and they are easy to confuse by merely bringing up the name of Jesus.
