A man died and went to Heaven. There were thousands of other people there. They were all naked and all looked as they did at the age of 21. He looked around to see if there was anyone he recognised. He saw a couple and he knew immediately that they were Adam and Eve.
How did he know?

Similar to the question I had. How about the pre-marital sex issue. Obviously, since they were the first, there was no official (pastor, reverend, minister etc.) to marry them, nor any witnesses to make it legal, so how did they procreate without ending up in the bad place?
