To be honest I don't think we'll ever come into to contact with them. 2 light years is a massive distance, will take ages even if we get anywhere near to the speed of light, I'm not if making such trips in a short enough time to make it worthwhile will ever be feasible.
Nevertheless it would be fascinating to see what life is like there. There could be so many new concepts unknown to us in every aspect of life: culture, language, law, religion, music, story telling, geography, nations, wars, martial arts and sports. If there was intelligent life, they could have very different ways of doing all of these. Also depending, on how old the planet is, there may be no intelligent life. "Intelligent life as in full sized animals has only existed for a fraction of the Earth's history, and the whole of human civilization has only existed for a miniscule fraction of that. If there was civilization, it could either be just beginning, extremely advanced, or have destroyed and build itself back up many times over.
