What would you say to an Alien?

Recently I read a thread on Above Top Secret, about what the best thing would be that you could say to an alien. I don't even have to think long to come up with an answer to that question.... I would ask the Alien on his Perspective (or his planet's perspective) to our planet's History, and evolution, with special Interest in many subjects, which are not clearly proven up to date. Other that that, I would obviously try to make it clear to him (or her) that I do absolutely not want, or intend any type of violent behavior toward him or her. I would also try asking about technological progress on any to him known planet(s).
What would you ask him? Do you disagree with any question of mine?






EDIT: Thank you for your Comments!
- I assume that a planet which is capable of sending spacecraft to our planet, would probably have knowledge about the places they send them to.
- I find your questions very very interesting, and after reading your comments I would probably add your's to my personal list too. ;P

What exactly has actually been causing all the Natural Catastrophes lately?

Lately I have been wondering alot what suddenly causes all of these natural catastrophes, which have been happening lately. How is it that a year ago, there was barely anything happening at all. Of course there were a few Occurrances, but nothing abnormal or so. This year although, is a very very Genocidal year to many countries of this world. We have Floods in Australia, War in Iraq, War in Afghanistan, almost a Wall-street Breakdown, a big Co2 Problem (?), and in my favorites last but not least:
The Avian Flu, which has mutated, and become pretty dangerous. (atleast dangerous enough for the US-Govt. to invest 7 million dollars in finding and developing a cure to it.) Now, if I am not missing out on anything, I would conclude allof these problems to "Chemtrails". They have been a Phenomenon, which has strongly increased in the last few years. There have literally been people from every single Country in the World making Reports of sightings on the Forum "AboveTopSecret.com". Take a minute to think about this now, We are told that Chemtrails are being used to cause artificial Rainclouds. What happens to Clouds naturally? they move.....
I am not saying that this is the only possible solution to everything, but it atleast would make sense in combination with theories claiming that there will be a "Depopulation" occuring in the next few years.
Has it begun?
