In Googling today who was the first liar, I came across this article. I thought some of the hypothesis in the article were interesting. He does address the flood and his opinion that it wasn't global. I think LCash as a geologist believed the same thing didn't he? And that Adam's creation was the story of the kingly lineage, and not him being the first human made. In addressing that he brings up as others have that who were the people Cained feared? How could have there been that many people on the earth when Cain said that? Etc Etc. Anyway, just posted for interests sake if anybody wishes to address anything in it. I kind of skimmed it but didn't read it in detail, so I don't expect anybody else will. lol.

Was Adam the First Human?
The creation of man in Genesis has always been read to mean that Adam was the first human God created. Why is that exactly? This isn't stated anywhere. In fact, what it actually says is that God created humans on day 6 of the creation account in chapter 1, then God rested on day 7 at the beginning of chapter 2, then comes the story of Adam's creation. It's nothing more than an assumption that these are two tellings of the same event.
For most of recorded human history, it really didn't matter. The events listed in the creation account were of little consequence. Whether God created all the earth in six days or in 4.54 billion years was irrelevant as there was no way of knowing one way or the other. There wasn't any reason to even suspect it was any different than how it read, and the overall message of the Bible didn't hinge on it.
Today, it does matter. In these modern times, we now understand more about the history of the earth and humanity than ever before. Modern understanding has proven to be in direct conflict with traditional interpretations of Genesis. This has resulted in many rejecting the Bible as nothing more than mythology, and many others rejecting modern wisdom and scientific progress as false.
The creation versus evolution debate has come to be one of the most divisive topics we face. Many people of faith fight tooth and nail to keep topics like evolution out of the school curriculum, and many others don't see why their children must remain in the dark because some people can't let go of their old religious beliefs.
The interpretation that says Adam was the first man in existence is the primary misconception that makes the Bible and modern science seemingly incompatible. Correcting this one small error takes pre-flood Genesis out of the realm of mythology and plants it firmly into known history...
