If we find a perfect planet, one with flourishing life and everything we need, wouldn't the germs kill us?

In theory, possibly. In reality, no. Before we colonized any inhabited planet, we would undoubtedly conduct an extensive series of experiments to determine any biological threat, and create appropriate preemptive measures. Alien viruses and bacteria *might* not even be compatible with our physiology, and were that the case, they would not pose any threat at all to begin with. "It just doesn't seem realistic that we'll ever have another home." According to my calculations, life exists in no fewer than 1%, but also no *more* than 5% of all 2nd Generation star systems. 95% of the planets we would colonize (and that's only the ones in the habitable zones) would be barren of life, and would require terraforming, which would involve us transplanting our native ecosystem, and thus would obviously pose no threat to us.

They'll also have no resistance to antibiotics, so we'll be fine.

possibly, however, we may find out that they are relatively primitive, undeveloped germs that can't damage us at all

Its just like in war of the worlds. I don't know if you read the book by H.G Wells, or watched the movie even, but in the book, and all the other versions, the only thing that really kills the aliens that are attacking in the viruses and bacteria that our kind has overcome over the past million years. It would probably be the same on another planet, and we would be so much smarter to just not try to inhabit another planet.

Your argument carries one big flaw. You assume that when and if we ever find life elsewhere, and when and if we are ever able to go there, we will still be little biological animals like we are at present. Bzzzzt. Wrong! Technology in the biological sciences and robotics/information sciences is progressing at such a huge rate that by the end of this century there will no longer be any necessity for humans to be based upon biology. We will have the ability to migrate to a robotic body. It may sound like science fiction, but so is space travel. be assured that it is FAR easier to make ourselves fully robotic than what it is to travel to other planetary systems. So if we ever venture beyond the solar system, it will be so far into the future that we will have shed our ancestral biology and will be immune to bacteria, virus or other biological threats. Cheers!
