hi my friend harregare long time no see
so about ur question
there is no another planet and it will not be so dont bother ur self

nothing will change no matter ppl move there or not. even the planet has perfect condition for human. since human start civilizition,a great number of knowledge has been accumulated and our planet has been changed but the nature or morality  of human has change nothing. so even though we move to another planet we will extort  the nature again and it is just retrace the history of earth again.so if there is another planet i wont move.it is not the way to make a difference

 & maybe after 25 years (If I still alive) I'll take my children to pass the summer's vacation there.. That time, I'll be enougn muture & maybe thinking about retiring.. So I'll have enough time to learn the aliens' language or whatever..

 Would you want to go there? Well.. I, honestly, think that it'll cost me a lot of money to go there. So I prefer to stay here in my mother earth .. But I'll try to communicate with aliens if they exist using the internet (in this case it must have another name)!
