BS, Why would a 'hostile' alien race attack us?

Logically they would wipe us out without effort using unknown technology. So why wait until now, after we have fucked up all our resources (Earth), if they could have managed them in a better way?

And btw, those 'distractions' are real and happening right now. Radiation is expanding, the proxy war at Syria is turning bigger and dangerous, the corruption of the governments all around the world is becoming ridiculous, etc...

I guess we humans need any excuse to keep the head down and not fight the 'evil' of this life. we'd just rather wait for a saviour or just watch our planet burn (but who can blame that, it seems we just failed).
