Sorry, MisCris. At age 27, this probably looks like tongues to you. The Jews wouldn't even teach this to people under 50, because it just confused them. I'll try what I can: the Hebrew words in the OT do not translate well into English, so there has been a lot of bad teaching, especially when they treated everybody like children, as some churches did for many centuries. Genesis 1 deals with God's plans, sort of like archetypes. Genesis 2 deals with the fulfillment of those plans. God envisioned man as one creation, all of us, from all time. That's what Genesis 1 is saying. Genesis 2 through the rest of the Bible is how it worked out on earth.
Let's try explaining time as a fourth dimension. Think of people living on a sheet of paper (two dimensional). The paper is falling from a great height, and takes several years to fall (low gravity, lol), so the height, the third dimension is not part of the paper. Each person is a different color, so we can watch them easier for our thought-experiment. The people on the paper think time is passing, so year 1 is at the top of the skyscraper it fell from, year 2 is at the highest floor window, etc. Over the years, the people have babies, and die. As the paper falls each person makes a mark in the air for wherever he was at that "time" (height). You look at this event when it is all over, and you can see where the red person was, the blue person and so on, because the marks they left behind, hanging in the air, look like tangled ribbons in the air. Every few floors a new color person appears (was born), and every few floors a ribbon ends (person died). Now, God can see us the same way. Except He made all the ribbons and put each one exactly where it was supposed to start (on the sixth day). He can see our whole life, however much our ribbons got tangled on the way down. That's how He can make us all at once, and still make us all be at a different time in what we call history. Genesis 1 is where it talks about how He put the ribbons together, and what kind He used.
That's not perfect, as it leaves out all of free will, salvation, etc., but it's kind of the standard way of viewing space/time our culture uses in place of the Hebrew translations.
