Who destroyed earth then?
These guys. The logo below is the more commonly seen version in Galactic Common Tongue (GCT).
GENIZIX is a multi-species alien organization specializing in weapon-making. They are well known for committing atrocious acts against literally every living thing. Ethics and morals are foreign concepts to them, but profit isn't. They're the most powerful group in operation, and the Wider Galactic Community can do little to stop them when they have more members than three times Earth's population.
Earth was already on a path to destruction before Genizix arrived, due to a cascade of tipping points in the climate system. Genizix exploited this weakness - and started a war with humanity to lessen the population for convenience before they kidnapped the survivors. Once the job was done, they reduced Earth to floating piles of space debris with their highly advanced tech. Some say they did this to hide the evidence of their crimes, and others say it was to frame post-humanity as their own creation. Either way, Earth wasn't the first planet they've destroyed, and it certainly wasn't the last.
