Logistics...............what would they be..........

Radiation.............solution needed

Viruses ...........oops

Drive..............how to travel light years without being light.

Cost effective result.................what could hyper-genius learn/gain from us?

Drag.............time delays in comms back home?

Gravity.................how to overcome the dif and live.

and so on

Sure would make a great invasion psyop though.......tie it in with mistranslations of Dagon myths....Annanaki..........pull an extermination event.....horde tech and information, and ...........voila..........God-men once again.

Just like the good old days.
