The problem with all the ET options is that it requires there to be few enough aliens that we can’t detect them, enough aliens that they randomly find us, technologically advanced enough to find us, get here, and not get cat Iggy yet dumb enough to get caught by US government. It’s such a narrow threshold made so improbably by how they find us.

I could buy water people. The ocean is ####ed. Time travellers? Plausible.
Ancient civilization that left and returned doesn’t make sense, though. There’d be some leftovers I think. Maybe they are just an incredibly tidy people.
