So, the best bet to find something would be in space. Even then it's not a sure thing. Orbits can change and something could end up impacting something else, fall into the sun, or flung out of the solar system.
The Lagrangian points (/ləˈɡrɑːndʒiən/; also Lagrange points, L-points, or libration points) are the five positions in an orbital configuration where a small object affected only by gravity can maintain a stable orbital configuration with respect to two larger objects (such as a satellite with respect to Earth and Moon).
The Lagrange points mark positions where the combined gravitational pull of the two large masses provides precisely the centripetal force required to orbit with them. A satellite at L1 would have the same angular velocity of Earth with respect to the Sun and hence it would maintain the same position with respect to the Sun as seen from Earth. Without Earth's gravitational influence, a satellite of the Sun, at the distance of L1, would have to move at a higher angular velocity than that of Earth.
I have been told by someone I know who is a scientist, worked at Lockheed skunk works and Lawrence Livermore labs that there have been at least 3 advanced civilizations that have existed on Earth and long since left or wiped themselves out.

a reply to: nukedog
Nukedog and Hanslune,
Sorry I do get carried away and for lack of a better description lack eloquence at time's in the way I phrase thing's, I got too over the top with the Jargon.
What it condensed down to is that I was saying the science is solid but it has limited data and therefore is not conclusive about that period in time, in fact we may know more about mars today than we do about the earth back then just like our lack of understanding of the ocean bed.
I will leave it there before I come out with more nonsense.
Oh and my hair is brown but other than that pretty damn close.
