How the hell would he know.,(reply>), Kaku has a point. If they are so advanced than we are , what could we possibly have that they would want? They would have resources that are infinite or more resourceful than ours. I believe if they have any interest in us/Earth its because they are studying us and our planet. I'm sure they are intrigued how creative we are and what we achieved in such short time. But to them we are probably like the way we look at ants. Just nearly not curious enough about us.,(reply>), He said “how the hell would I know”,(reply>), Your right bro nobody knows! They will probably just eat us! Or kill us for our resources just like we would do to them!
