Hasn't this already happened? (Though I haven't heard much of it recently, so it might have just been a false finding, or they might still have to be doing tests on it to find out.)

If we find them first, it means that we are far more advanced than they are.
The fate of the Aliens depends on whether a group of scientists find them, or a bunch of land-hungry colonists. They better hope it's not the latter.

If they're less technological than us we'll proboly take their planet & put them on a horrible death moon of a reservation, like the Native Americans, on greener. This is of course if they aren't horrible insect aliens like in "Starship Troopers". ( The book, not the movie)

The chemistry of living things on different worlds will probably be similar since earthlike planets will probably start out with similar atmospheres; mostly nitrogen, carbon dioxide, ammonia, methane, water vapor, and hydrogen, with no oxygen. Pass lightning through it and you get the same thing no mater what world you're on; amino acids, sugars, nitrogeneous compounds that make the code carrying parts (Adenine, Thiamine, Cytosine, and Guanine) of nucleic acids, coenzymes ,("vitamins") etc. The only chemical differences will be in the details. For example, on earth, the backbone of DNA and RNA are based on phosphate ions and 5-carbon sugars. (ribose, Deoxyribose, etc.) On another world, nucleic acids might have a backbone of sulfate ions and 6-carbon sugars. (glucose, fructose, etc.) Amino acids that make up proteins might also differ slightly. Some amino acids may be universal since they were very common in the primordial soup. (glysine, alanine, lysine) But the rarer amino acids, like methionine, tyrosine, aspartate, phenylalanine, etc. on earth, would differ. The major differences will be in the form of the organisms. no intellegent species will look similar to us, that takes far to many doses of convergent evolution.
