Was she 800 million years old?

[Snarl]

800 million years ago, the land on Earth was barren, devoid of any life at all. All of Earth's life at the time was in the oceans. It wasn't until around 550 to 540 million years ago that life migrated from the oceans and puddles onto dry land starting with plants (see "Rhynie chert" for the very first land plants) and graduating to insects and later amphibians. This means that the Princess, if 800 million years old, had to come from somewhere other than Earth, which is not entirely impossible.

Thanks (greatly) for your personal observations.  You're a brilliant man.

Some folks believe the Earth is ~4.5B years old.  It's hard to imagine when 'life' might have cooked itself up.  Hard to imagine what caused life to 'happen'.  Might have happened more than once.

Just imagine if the Earth had been around for 16B years, and it was just the moon's impact that reset the clock to 4.5B years ...  Saw a really impressive video dissertation of that a good while back.  Erased anything definitive I had ever been taught.  No?
