Sending a message to Glies581d

Astronomers announced that they think they've found an extra-solar planet, that might be earth like, and it's only 20.3 light years away in the constellation of Libra.
They are asking the people of earth to write messages to send from the radio dish in canberra Australia.
There are so many things to say to whatever beings might inhabit this planet. However, each message can only be 160 words long.

I so badly wanted to put down:

Greetings my fellow travelers in this comsos that the great creator has placed us in, and hope your journey thus far has been peaceful. Peace is a prize that is beyond measure. On our world, we have have more land than we can possibly use, and have the ability to feed everyone here, but due to corruption by people in power, we destroy the very land that can sustain us. We have the potential to be such a giving people, yet we are selfish. We have the technology to travel to other planets in our solarsystem, but the governments keep that power to themselves. We have water in abundance, yet people die of thirst, and we have the means to grow more than enough food to feed everyone here, yet we let people starve to death. We would dearly love to shake hands with our fellow earth people, yet we can not agree on the basics of human rights, such a life, liberty, and property. We still have people who fight to the death (or blow up innocent people) over words spoken and written 1500+ years ago. We have governments that imprison people for speaking their minds, and we have people, who in their quest for power, kill anyone that gets in their way.
If peace is what you are looking for, give us a hundred years or so. Maybe by then we'll be at peace with ourselves, or we'll all be dead, and you can have our world.

Instead, what I wrote was:
Peace is a price we all seek. Our world has an abundance of natural resources, still we fight instead of working together. We wish you peace, and long life.

I quess that in 160 words, I couldn't put down what I really wanted to say. Maybe I should have said, "Stay the heck away from earth. If you show up, our government will shoot you, stuff you, and stick you in area 51."
