Ok you all figured it out.

The real reason we are on Mars is because the Martians killed themselves off in a great Nuclear war during the mid 1800's when dude (Lowell) saw the canals and stuff their. He was on the money. But when the other guys started noticing things it was clear they just doomed themselves right off the planet. I even heard rumours that vegatation was also seen on that desert world. See this proposes some new questions about water. Thats what the canals (rivers) were for. They were for water from the poles.

There were several castes of Martians. The aristocracy, ther artisans, and the peasants. While the peasants revolted due to the hard treatment they recieved by transporting the water and to solve the problem on not loosing control, the aristocracy nuked the planet in order to maintain the status quoe. Kinda like John F***ing Kerry wants to do.

See really we are there because we did find an ancient civilization there. thats why they kept visiting the Earth. They new they would have to alter our enviroment to suite them. That is what they are doing right now. Changing our enviroment so they can invade in the near future.

I believe they made a movie about this not too many years ago about the eventual take over of earth and John Kerry is behind it.....
