I had bet on zombies for the Dec 2020 final stage but I guess intergalactic war would have fit the bill too
As if our weapons would do anything to alien craft lmao
It's not space aliens, it's some other group of humans from another country or non-aligned organization.
Considering the amount of evidence provided, there's no way to be sure its 'some other country'. It could be US citizens, the US armed forces, or hell, an ET. Safe to not make assumptions.
What kind of odds are you willing to give me that it's actually space aliens?
