Seriously, give up the idea that science fiction has put in your head. We can't just merely "make contact" with them. It's a lot more complex than that. It's hard enough to send messages to satellites orbiting the Earth. Messages to this other planet would take centuries just to reach them.
The chances that there is intelligent life on this planet is pretty good, since the conditions suggest that it's a similar planet to Earth, but any contact or anything we may have with them isn't likely in the near, or even distant future.
