Adam was the first of modern mankind, and the sixth advent of humanity that God put on this Earth. Yehovah created the institution of marriage, with its components being a male and a female. They were formed to concatenate, integrate, interact, and mate together, with the possibility to procreate offspring. For example, a plug (male) fits into a socket (female), to provide power to an appliance. Trying to join two plugs or two sockets together produces nothing but aggravation and frustration.
