Re: Aliens May Exist But Contact Would Hurt Humans; Hawkings
"Because I also think there are also intelligent war like alien societies like us as well. Who may also be around our technological level."
Surely it's unlikely we'll ever travel much further than our solar system due to technological constriants, in my opinion. Therefore any alien societies that are intelligent AND travel here, will have technology (which would have to be beyond our comprehension) far in superior to our own and simply wipe us off the face of the universe if they so want to.
NOTE: I don't believe its very likely there are any intelligent aliens.
