You couldn't kill the microbes found five miles underground, even with billions of hydrogen bombs, but I doubt that the aliens would find them a threat. My solution would wipe out the entire chain that starts with photosynthetic plants, but mushrooms would probably survive. | |

I think that would even boil the oceans. Earth's oceans take 10^27 J to boil (roughly). A KT is 4*10^12 J; need 10^15 KT of nukes to boil a planet's oceans. (TT is 10^9 KT, a billion of them is 10^18 KT, so a 100x safety factor). We could already build TT nukes; making a TT nuke factory in their system seems plausible. | |
