Questions about Pre-Earth Life...

How do dinosaurs fit into the picture?
Did they live on the earth?
Did they live after Adam/Eve?
How come the earth is billions of years old but from Adam it is only 6,000 years?
How could Adam/Seth/ other Biblical people live to be 900 years old? Does that make sense?

Well, here is my understanding and postulation. These are only my thoughts.

There was no death before the Fall of Adam because the world and Adam and Eve were in Terrestrial world. Adam has a belly button because HF and HM had him and Eve - they are his literal and physical descendants. Sorry - I don't believe that evolution led to mankind. Also, I believe there are animals in heaven, in a perfect form who had the animals in the Garden.

I think the Garden was in a different place than where our earth is now. It was closer to God/Kolob. The fall is actually just the Garden moving away from God and onto the earth where we are now.

This earth is billions of years old. There was evolution here, wild animals, and yes, even the dinosaurs. But, 6,000 years ago, Adam and Eve came and began inhabiting the world. The rest is history and we know the story.

Thoughts?
