Wow, Gives a great sense of the time that has passed. I suggest using your mouse wheel but don't drag the scroll bar, you will lose the sense of enormacy

1,485,000,000 phere. Land

1,484,000,000 began to rust.(1)

Well you get the idea

From time to time I find your comments on the web and enjoy your point of view. I wrote the timeline you clipped from geocities. Geocities has closed and I have moved the site to:
www.angelfire.com/planet/check/earth.html
I have made many changes to the site and I invite your comments.

Eathviewer that new page is awesome - nice additions - Its now bookmarked in my education tab. The page really gives you an indication of how small we really are. What relly throws ones mind into a boggle is that our star is in main sequence and we are only 1/2 way thru its life.
Plus the fact that our star is a 2nd or 3rd generation star in the universe which means its timeframe is but a fraction of the universes timeframe. It is just mind-boggling to think about. In less than 7 billion years everything ever created on out planet will be gone. This living spark of life that the universe morphed into will become silent and forgotten. Like a fleeting moment of brilliance. What will become of the energy that makes up our essence?
