life exists elsewhere in universe..?

thinking whether intelligent life elsewhere in universe..wht say..?..if der is any intelligent life like dat in star trek..im sure they have explored and contacted us..but it seems dat we are the only one's upto now..with an average of 5 planets per star..hmm that approximated..half a trillion stars in our solar system and an estimated 100 billion (KNOWN!) solar systems..we have 2.5*10^23 planets in the universe..this number will definitely continue to grow as our telescope technology improves..but i would say that the odds of not existing an intelligent life elsewhere in universe is 1..i mean probability.. It's kind of like trying to roll a dice a hundred times without hitting a '1.'..you know dats kind of impossible..der must be life elsewhere in universe.. i mean you have to hit something eventually..especially different types of life like microorganisms..which can survive in fierce environments..with so many planets, advanced life is very probable elsewhere..problem is..the light emitted from earth takes billions of light years to reach the further planets..so if they somehow saw us through a telescope..someone like sentiens in matrix..hehe..that activity will have been from billions of years ago..life will be long since gone by that time..ahh..anyway..progress will be difficult..considering that the closest habitable planet is 25 lightyears away..if we can manage to send colonizers..we will probably never speak to them again..since any light-based communication will take 25 years to reach us..and it will take just 50 years to travel..huh..untill then the colonizers will die eventually..we will have to find a way to break the universal speed limit which is the speed of light if we want to overcome this obstacle..still..another prob..relativity will hold for those who travel and we will age relatively faster and will be dead sooner than them..again..a problem for communication..damn this communication..no wonder how hard u study principles of communication..dis is surely a pretty hard puzzle..im working on this post 3 days finally iam goin to post this..well..i hardly spent 30min to this in each day..hehe..
