Humans Vs the Aliens

Aliens really possess no threat to the mankind on the whole. Considering the worst case scenario where the sight of a Low Flying Alien craft in the neighborhood being quite frequent; the aliens cannot out win us.

I strongly believe that no alien race has evolved to be too powerful (or) can bring a mother ship with billions of soldier aliens in it : )

We are here for a reason and no alien race can make it no sense.
