Wouldn't an alien attack be AWSOME?

i hope it happens like halo, we have too fight them and humanity bands together so we can have better space defenses, actually, being mature for a second, an alien invasion would make humanity stronger and make earth safer because if the whole world pulled together to make better space crafts, so if meteors and things like that also attacked us, we could deter it. plus we'd fight bad-@$$ aliens
