Under Area 51 there is a base the size of 2 football fields. In one of the rooms in this base, there are gray alien embryos in capsules. This gray alien species has no sexual organs and cannot reproduce, so they give birth to new babies in capsules and do the same in our world. This alien species is the one in the photographs shown above by Boyd Bushman. In addition, scientists working in that area try to produce new technologies by bringing spacecraft that have crashed on Earth to Area 51 and analyzing them. There are many more studies like this, but I can't tell you about them because of strict rules. Their work is usually related to aliens.
