Seeing how incohrrent and fractured humanity is, we’d meet them with a jumbled mix of:

• Rabid xenophobia
• Aggressively trying to convert them to a dozen of our different religions
• Forming multiple cults worshipping them as gods
• Creating a shit load of really weird rule 34 AI-generated porn focused on them
• Dismissing their existence as some sort of a deep fake conspiracy
• Trying to sell them some worthless shit for a massive profit
• Trying to sell them fellow humans as slaves
• Trying to steal their technology to conquer the galaxy
• Flooding then with brainrot memes for the lolz
• Trying to destroy them with conventional weapons

And they would see all this and either destroy us in disgust or get the hell out of the solar system ASAP and cordon it off with hazard signs.
