Spotting Adam and Eve

A man dies and goes to heaven. There he sees an assembly of hundreds of people both male and female, in their birthday suits, ( i.e. they were not donning any dresses on.) amongst which stand Adam and Eve. He immediately recognizes them. How did he do it?

Answer:

He recognized Adam and Eve as the only people without navels. Because they were not born of women, they had never had umbilical cords and therefore they never had navels.

NOTE: Puritannical, conservatives and die-hard fundamentalists of theological schools, kindly excuse me for the above explanation.
