Two scenarios that may/may not happen.

[Fake Messiah]

It doesn't. So why do bible literalists believe it is?

Misinterpretation.

Genesis 1:1 states:

In the beginning God created the heaven and the earth.

This is simply stating that God created the universe and the earth PERIOD. There is no mention of how long it took...

The 7 day period only relates to God making the earth habitable and seeding it with life, so In order to interpret the earth as being 6000 years old, you'd have to believe the bible is speaking of that 7 day period as literally 7 days (which is most likely why you referred to them as literalists), except the Bible makes it clear that God measures time differently than we do (which makes sense because time is relative).

For a thousand years in thy sight are but as yesterday when it is past, and as a watch in the night. - Psalm 90:4

But, beloved, be not ignorant of this one thing, that one day is with the Lord as a thousand years, and a thousand years as one day. - 2 Peter 3:8

So without taking anything else into account and going by just the numbers of the bible it's at THE LEAST 13,000 years from the beginning of the 7 day period till now.

This means Adam was hanging around for what could've been just under 2000 years before the 7 day period was over, seeing how he was created sometime during the 6th day (keep in mind this is a thousand year period) and Eve wasn't formed time sometime AFTER the seventh day.

What we DON'T KNOW is:

1. How long was Adam hanging out by himself when God decided to create Eve.

2. How long Adam and Eve were together before the fall.

Well, Huggy, you're becoming desperate as fuck because Bible seems to be specific as though there were some chance that the word "day" might be misinterpreted, the verse carefully states "the evening and the morning," as though to emphasize that it was one twenty-four-hour period and no more. The day referred to in this verse is still taken to be the familiar twenty-four-hour day and nothing more by Jewish and Christian fundamentalists today:

Genesis 1:5 - And God called the light Day, and the darkness he called Night. And the evening and the morning were the first day.

Indeed, until the 19th century, there was never any question about this. It was universally assumed that the days referred to were literally days-twenty-four-hour periods. In the 19th century, however, it became more and more clear that Earth was millions of years old, and in almost the first retreat from the literal acceptance of the Bible, there began to be some hesitancy about those "days."

And what's even worse is that this 24 hour and 7 day system is now known to be taken from the Babylonian system to which he writers of the Genesis were influenced by this Babylonian custom and adopted it. The story begins before Babylonians with the people of the Tigris-Euphrates who had developed a lunar calendar probably before 2000 B.C. The appearance of each new moon, signifying the start of a new month, was the occasion of a religious festival, and eventually other phases of the moon were celebrated. It was the full moon that was first called "sabbath" (sabbatu to the Akkadians, who dominated the Tigris-Euphrates valley in the third millennium B.C.).

Then Babylonians started celebrating the intermediate phases of the moon. Each phase comes at an interval of not quite 7.4 days, so that in order to keep the week in time with the lunar months, the week should be sometimes seven days long and sometimes eight in some set pattern. So the Babylonians chose to make the week an unvarying seven days long, even though this meant that the week lost all connection with the lunar month. The reason for this was that there happened to be seven "planets" in the sky that changed position regularly against the background of the fixed stars: the sun, the moon, Mercury, Venus, Mars, Jupiter, and Saturn. And indeed we still have these names in our names for the day: Sunday - Sun Day; Saturday - Saturn day; Monday - Moon day; Thursday - Thor's day etc.

To the Babylonians, it seemed to make astrological sense to suppose that each planet was in charge of a particular day (since each planet was in turn the province of a particular god). An eighth day in a week would be a day without a planet-god in charge, and this was unthinkable. The Jews in Babylonian exile naturally observed the weekly day of rest, but could not accept the polytheistic religious justification and had to evolve one of their own. So Jews only celebrated one day (Saturday), then Christians came and celebrated Sunday; then Muslims came and celebrate Friday. You see how still people celebrate days as some sort of deities? The writers of the Genesis therefore grounded it in the week of creation-six days of divine labor and one day of divine rest. It was a case of the labors of God himself being made to fit the Babylonian week. That is why Creation took six days rather than any other number of days.
