If aliens attacked with a full scale invasion Earth would probably be overwhelmed within hours. Depending on what they want or what drives them to invade Earth they may do a number of things. If they want slaves they'd probably take out all of our communications, systematically wipe out our military and then round up civilians. If they just want our resources they'd probably use some sort of virus or nanobots o specifically wipe out humans.

Thare is an about 1percent chance that aliens are real and about a 0percent chance they will attack us because they are mostly 1.0000 light years away.
