Why NASA didn't send A Worker with their Rovers to Mars Mission?

If they come to us, then that means they've obviously advanced in technology far past us, considering we just recently made it to Mars. If that's the case, and they come to us, if they do not want us here anymore, we kind of have no possibility of defending ourselves.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
